McHUGH, Justice:
This case is before this Court upon four certified questions
from the Circuit Court of Jefferson County regarding whether the employing entity in this case is an “employer” under
W.Va.Code,
5-ll-3(d) [1994] of the West Virginia Human Rights Act and, if the employing entity is not a statutory employer, whether the plaintiff can nevertheless maintain a sex discrimination claim under the Human Rights Act directly against her supervisor. We are also asked to address whether the plaintiff can maintain a cause of action at common law against her former employer for retaliatory discharge based on alleged sex discrimination or sexual harassment.
The certified questions, as well as the circuit court’s answers to them, are as follows:
I. Question: As to whether an entity is an ‘employer’ under the West Virginia Human Rights Act, should the Court follow the standard contained in 42 U.S.C. 2000e(b) in determining the applicable period of time during which twelve or more persons must be employed?
Answer by the circuit court: Yes.
II. Question: Is the Coalition for the Homeless of Jefferson County, West Virginia, an ‘employer’ within the definition of the West Virginia Human Rights Act?
Answer by the circuit court: No.
III. Question: Can an employee maintain an action directly against her supervisor for sexual discrimination/harassment under the West Virginia Human Rights Act for actions of a ‘statutory employer’ even though the employer of both the accused supervisor and complaining employee lacks a sufficient number of employees to be subject to the West Virginia Human Rights Act?
IV.Question: Can an ‘at-will’ employee maintain a tort action at common law for retaliatory discharge based on allegations of nonphysical sexual discrimination and/or harassment?
I.
FACTS
The following relevant facts of this case are undisputed and have been stipulated by the parties:
The Coalition for the Homeless of Jefferson County, West Virginia, Inc. (hereinafter “Coalition”) is a non-profit corporation with its principal place of business in Jefferson County, West Virginia. Plaintiff Sharon N. Williamson (hereinafter “plaintiff”) was employed as the Coalition’s office manager and bookkeeper from September 9, 1994 until March 31, 1995. She was an at-will employee. During the time of plaintiff’s employment at the Coalition, the Coalition also employed defendant Warren 0. Greene as its executive director and plaintiff’s immediate supervisor.
In March of 1995, the Coalition, through Defendant Greene, informed plaintiff that her employment was being terminated on March 31, 1995. Plaintiff subsequently filed a complaint in the Circuit Court of Jefferson County, alleging that Defendant Greene committed certain nonphysical acts and misconduct constituting sexual harassment by creating a discriminatory and/or hostile work environment for plaintiff based upon her sex.
Plaintiff further alleged that she was terminated in retaliation for her opposition to Defendant Greene’s unlawful sexual harassment and discrimination, in violation of the
West Virginia Human Rights Act,
W.Va. Code,
5-11-1,
et seq.
According to the Coalition’s records, in 1994, it employed, including plaintiff and Defendant Greene, twelve or more employees during the weeks of June 19 and June 26.
The Coalition’s records further indicate that in 1995, it employed, including plaintiff and Defendant Greene, twelve or more employees during the weeks of September 3,10,17 and 24, October 1, 15, 22, and 29, and November 5,12,19 and 26.
The above questions were certified to this Court by order entered April 19, 1996, pursuant to
W.Va.Code,
58-5-2 [1967].
II.
STANDARD OF REVIEW
In syllabus point one of
Gallapoo v. Wal-Mart Stores, Inc.,
197 W.Va. 172, 475 S.E.2d 172 (1996), we stated: “The appellate standard of review of questions of law answered and certified by a circuit court is
de novo.” (citing Simon v. G.D. Searle & Co.,
816 F.2d 397, 400 (8th Cir.),
cert denied,
484 U.S. 917, 108 S.Ct. 268, 98 L.Ed.2d 225 (1987).)

197 W.Va. at 174, 475 S.E.2d at 174.
III.
DISCUSSION
A.
As indicated above, certified questions one and two involve the definition of the term “employer” under
W.Va.Code,
5-ll-3(d) [1994] of the West Virginia Human Rights Act and application of that statutory definition to the employing entity in this case, the Coalition.
W.Va.Code,
5-ll-3(d) [1994] provides: “The term ‘employer’ means the state, or any political subdivision thereof, and
any
person
employing twelve or more persons within the state:
Provided, That such terms shall not be taken, understood or construed to include a private club[.]
” (footnotes and emphasis added).
Both the plaintiff and the West Virginia Human Rights Commission (hereinafter “Commission”), as amicus curiae, maintain that because
W.Va.Code,
5-11-3(d) [1994], quoted above, does not specify a time period during which an employing entity must employ twelve or more persons within the state in order for such entity to be an “employer,”
W.Va.Code,
5-11-3(d) [1994] should be construed broadly to accomplish the purpose and objective of the West Virginia Human .Rights
Act.
W.Va.Code,
6-11-15 [1967] (“The provisions of this article shall be liberally construed to accomplish its objectives and purposes.”
Id.
in relevant part);
Skaff v. West Virginia Human Rights Com’n,
191 W.Va. 161, 162, 444 S.E.2d 39, 40 (1994); syl. pt. 1,
Paxton v. Crabtree,
184 W.Va. 237, 400 S.E.2d 245 (1990). It is therefore their contention that
W.Va.Code,
5-11-3(d) [1994] should be liberally interpreted as follows: an employing entity is an “employer” under
W.Va.Code,
5-11-3(d) [1994] if it has employed a
total
of twelve or more persons within the state during the 365-day period preceding the filing of an administrative complaint pursuant to
W.Va.Code,
5-11-10 [1987], regardless of whether twelve or more persons were employed on any one day or during any one pay period.
In sharp contrast to the arguments of plaintiff and the Commission, the circuit court concluded that to be an “employer” under
W.Va.Code,
5-11-3(d) [1994], the period of time during which twelve or more employees must be employed by an employing entity is that period of time set forth in
W.Va.Code,
5-11-3(d) [1994]’s federal counterpart, 42 U.S.C. § 2000e(b) (1991), which specifically provides, in pertinent part: “The term ‘employer’ means a person engaged in an industry affecting commerce who has fifteen or more employees
for each working day in each of twenty or more calendar weeks in the current or preceding calendar year[.]”
(emphasis added).
In applying this federal standard to the stipulated facts of this ease, the circuit court apparently concluded that the Coalition did not employ twelve or more employees “for each working day in each of twenty or more calendar weeks in the current or preceding calendar year.”
Id. As
a result, the circuit court found that the Coalition was not an “employer” under the West Virginia Human Rights Act.
We agree with the circuit court’s conclusion that the Coalition is not an “employer” under
W.Va.Code,
5-11-3(d) [1994], However, the circuit court erroneously determined, as a matter of law, that the period of time during which twelve or more employees must be employed by an employing entity under
W. Va. Code,
5 — 11—3(d) [1994] is that period of time which is set forth in 42 U.S.C. § 2000e(b) (1991) (“for each working day in each of twenty or more calendar weeks in the current or preceding calendar year”).
We have indicated in prior eases that “[i]t is not for [courts] arbitrarily to read into [a statute] that which it does not say. Just as courts are not to eliminate through judicial interpretation words that were purposely included,
we are obliged not to add to statutes something the Legislature purposely omitted.” Banker v. Banker,

195 W.Va. 129, 464 S.E.2d 771 (1995);
Donley v. Bracken,
192 W.Va. 383, 452 S.E.2d 699 (1994)). (emphasis added).
See State ex rel. Frazier v. Meadows,
193 W.Va. 20, 24, 454 S.E.2d 65, 69 (1994). Moreover, “[a] statute, or an administrative rule, may not, under the guise of ‘interpretation,’ be modified, revised, amended or rewritten.” Syl. pt. 1,

See Sowa v. Huffman,
191 W.Va. 105, 111, 443 S.E.2d 262, 268 (1994).
These cautionary principles notwithstanding, the circuit court interpolated specific federal statutory language into our Human Rights Act. We find that it was error for the circuit court to do so, as we agree with the Coalition that
W.Va.Code,
5-11-3(d) [1994] is clear and unambiguous and should not be interpreted but instead, should be applied as written.
See Frazier,
193 W.Va. at 24, 454 S.E.2d at 69;
Craig v. City of Huntington,
179 W.Va. 668, 670, 371 S.E.2d 596, 598 (1988). This Court has traditionally held:
‘ “When a statute is clear and unambiguous and the legislative intent is plain the statute should not be interpreted by the courts, and in such case it is the duty of the courts not to construe but to apply the statute.” Point 1, syllabus,

Syl. pt. 1,
W. Va. Radiologic Technology Bd. v. Darby,
189 W.Va. 52, 427 S.E.2d 486 (1993).
W.Va.Code,
5-11-3(d) [1994] clearly and unambiguously provides that an “employer,” for purposes of the West Virginia Human Rights Act, means “any person
employing
twelve or more persons within the state[.]”
Id.
in relevant part, (emphasis added). As a matter of grammar and of logic, the use of the term “employing,” without more, refers to the time when the acts giving rise to the alleged unlawful discriminatory practice were committed.
Cf. Commonwealth of Pa. v. Kimmel,
523 Pa. 107, 565 A.2d 426, 428 (1989) (The term “ ‘[violating’ in the common usage of the term refers to the time when the offensive conduct takes place[.]”).
Thus, pursuant to
W.Va.Code,
5-11-3(d) [1994] of the West Virginia Human Rights Act, the term “employer” means the state, or any political subdivision thereof, and any person employing twelve or more persons within the state: Provided, That such terms shall not be taken, understood or construed to include a private club. To be an “employer” under
W.Va.Code,
5-11-3(d) [1994], a person must have been employing twelve or more persons within the state at the time the acts giving rise to the alleged unlawful discriminatory practice were committed.
According to the stipulated facts of this case, plaintiff was employed by the Coalition from September 9, 1994 until March 31, 1995. Although both prior and subsequent to these dates, the Coalition, during various periods of time, employed twelve or more persons within the state, it appears undisputed that during the dates of plaintiffs employment and at the time the offensive acts alleged took place,
the Coalition did
not
employ twelve or more persons. Thus, the Coalition was not “employing twelve or more persons within the state” within the meaning of
W.Va.Code,
5 — 11—3(d) [1994]. Under the facts of this case then, the Coalition is not an “employer” under the West Virginia Human Rights Act.
B.
The final certified question
concerns whether plaintiff can maintain a common law claim against the Coalition for retaliatory discharge for sex discrimination or sexual harassment. Certified question four, which the circuit court answered in the negative, is posed as follows: Can an “at-will” employee maintain a tort action at common law for retaliatory discharge based on allegations of nonphysical sexual discrimination and/or harassment?
As we determined above, plaintiff has no cognizable claim for retaliatory discharge against the Coalition under the West Virginia Human Rights Act because the Coalition is not an “employer” under
W.Va.Code,
5-11-3(d) [1994]. Plaintiff amended her complaint asserting that in the event the Coalition is not a statutory employer, she has a common law claim for retaliatory discharge based upon alleged sex discrimination or sexual harassment, pursuant to
Harless v. First National Bank in Fairmont,
162 W.Va. 116, 246 S.E.2d 270 (1978).
There is no dispute that at the time plaintiff was terminated from her employment at the Coalition, she was an “at-will” employee. Prior to this Court’s decision in
Harless, supra,
it was an established principle in this jurisdiction that an employee who is so employed could be discharged with or without cause.
Id.,
162 W.Va. at 119-20, 246 S.E.2d at 273
(citing Wright v. Standard Ultramarine and Color Co.,
141 W.Va. 368, 382, 90 S.E.2d 459, 468 (1955) and
Adair v. United States,
208 U.S. 161, 28 S.Ct. 277, 52 L.Ed. 436 (1908)). In
Harless,
however, we recognized the growing trend that an employer may be liable if he or she terminates an at-will employee in contravention of some substantial public policy:
[t]he rule that an employer has an absolute right to discharge an at will employee must be tempered by the principle that where the employer’s motivation for the discharge is to contravene some substantial public policy principle], then the employer may be liable to the employee for damages occasioned by this discharge.
Id.

See also Cordle v. General Hugh Mercer Corp.,
174 W.Va. 321, 325 S.E.2d 111 (1984).
We subsequently clarified the phrase “substantial public policy” in
Birthisel v. Tri-Cities Health Services, Corp.,
188 W.Va. 371, 424 S.E.2d 606 (1992), explaining that it was
designed to exclude claims that are based on insubstantial considerations. The term ‘substantial public policy5 implies that the policy principle will be clearly recognized simply because it is substantial. An employer should not be exposed to liability where a public policy standard is too general to provide any specific guidance or is so vague that it is subject to different interpretations.
Id.,
188 W.Va. at 377, 424 S.E.2d at 612. In syllabus points two and three of
Birthisel,
we held:
2. To identify the sources of public policy for purposes of determining whether a retaliatory discharge has occurred, we look to established precepts in our constitution, legislative enactments, legislatively approved regulations, and judicial opinions.
3. Inherent in the term ‘substantial public policy5 is the concept that the policy will provide specific guidance to a reasonable person.
Id. See also Roberts v. Adkins,
191 W.Va. 215, 444 S.E.2d 725 (1994);
Lilly v. Overnight Transportation Co.,

Shanholtz v. Monongahela Power Co.,
165 W.Va. 305, 270 S.E.2d 178 (1980).
The West Virginia Human Rights Act sets forth this State’s public policy concerning an individual’s right to equal opportunity in employment without regard to either sex, race, age, handicap, religion or national origin.
W.Va.Code,
5-11-2 [1989] states:
It is the public policy of the state of West Virginia to provide all of its citizens equal opportunity for employment,
equal access to places of public accommodations, and equal opportunity in the sale, purchase, lease, rental and financing of housing accommodations or real property.
Equal opportunity in the areas of employment
and public accommodations
is hereby declared to be a human right or civil right of all persons without regard to race, religion, color, national origin, ancestry, sex, age, blindness or handicap.
Equal opportunity in housing accommodations or real property is hereby declared to be a human right or civil right of all persons without regard to race, religion, color national origin, ancestry, sex, blindness, handicap, or familial status.
The denial of these rights to 'properly qualified persons by reason of race, religion, color, national origin, ancestry, sex, age, blindness, handicap, or familial status is contrary to the principles of freedom and equality of opportunity and is destructive to a free and democratic society.
(emphasis added).
The West Virginia Human Rights Act further makes it an unlawful discriminatory practice “[f|or any employer to discriminate against an individual with respect to compensation, hire, tenure, terms, conditions or privileges of employment[.]”
W.Va.Code,
5-11-9(1) [1992], in relevant part.
See Holstein v. Norandex, Inc.,
194 W.Va. 727, 730, 461 S.E.2d 473, 476 (1995). The term “discriminate” means “to exclude from, or fail or refuse to extend to, a person equal opportunities because of ... sex[.]”
W.Va.Code,
5-11-3(h) [1994], in relevant part.
Furthermore,
“W.Va.Code
5-11-9(7)(C) (1992), prohibits an employer or other person from retaliating against any individual for expressing opposition to a practice that he or she reasonably and in good faith believes
violates the provisions of the West Virginia Human Rights Act.” Syl. pt. 11,
Hanlon v. Chambers,
195 W.Va. 99, 464 S.E.2d 741 (1995).
W.Va. Code,
5-11-9(7)(C) [1992] states:
It shall be an unlawful discriminatory practice, unless based upon a bona fide occupational qualification, or except where based upon applicable security regulations established by the United States or the state of West Virginia or its agencies or political subdivisions:
(7) For any person, employer, employment agency, labor organization, owner, real estate broker, real estate salesman or financial institution to:
(C) Engage in any form of reprisal or otherwise discriminate against any person because he has opposed any practices or acts forbidden under this article or because he has filed a complaint, testified or assisted in any proceeding under this article.
The West Virginia Human Rights Act establishes a clear and unequivocal public policy against sex discrimination in employment and retaliatory discharge based thereon. Although the plaintiff in this case cannot maintain a claim against the Coalition for violations of the Act because the Coalition is not a statutory employer, the Act’s anti-discrimination policy is substantial and provides specific guidance to reasonable employers with regard to discrimination in employment.
Birthisel,
at syl. pt. 3.
In
Kerrigan v. Magnum Entertainment, Inc.,
804 F.Supp. 733 (D.Md.1992), a female employee discharged from employment two weeks after informing her employer that she was pregnant, alleged a common law claim for wrongful discharge based on sex discrimination.
Id.,
804 F.Supp. at 734. Plaintiff had no available statutory remedy because her former employer employed fewer than fifteen persons.
Id.
The United States District Court for the District of Maryland rejected the defendant employer’s argument that small businesses were excluded from the statutory reach of Maryland’s Fair Employment Practices Law and Title VII of the Civil Rights Act of 1964, as amended, as a “result of deliberate legislative intent to avoid burdening small businesses with suits alleging discrimination in employment.”
Id.,
804 F.Supp. at 735. The court in
Kerrigan
observed that although small businesses were exempt from the burdensome
administrative
requirements of the statute, it could find no evidence of “an intention to grant small business a charter to discriminate” or “exempting small business from [Maryland’s] anti-discrimination policy.”
Id.,
804 F.Supp. at 736. (footnote added).
In
Collins v. Rizkana,
73 Ohio St.3d 65, 652 N.E.2d 653,
reh’g denied,
74 Ohio St.3d 1409, 655 N.E.2d 188 (1995), the Supreme Court of Ohio determined that a source of express public policy prohibiting sexual harassment/discrimination could be found in that state’s civil rights statute which prohibits employment discrimination based on sex.
Id.,
652 N.E.2d at 659. The court in
Collins
emphasized that the plaintiff employee had no remedy available to her under Ohio’s civil rights statute because her employer never employed four or more employees, the requisite number of employees to bring him within the statutory definition of “employer.”
Id.,
652 N.E.2d at 660.
See Id.,
652 N.E.2d at 661 (“[W]e cannot find it to be Ohio’s public policy that an employer with three employees may condition their employment upon the performance of sexual favors while an employer with four employees may not.”).
See also Bennett v. Hardy,
113 Wash.2d 912, 784 P.2d 1258 (1990).
As indicated above, the West Virginia Human Rights Act clearly constitutes this state’s “substantial public policy” against sex discrimination and sexual harassment in employment, including retaliatory discharge based thereon. Although the Act does not provide this plaintiff with a statutory remedy,
it nevertheless sets forth a clear statement of public policy sufficient to support a common law claim for retaliatory discharge against an employer, such as the Coalition, exempted by
W.Va.Code,
5-11-3(d) [1994].
Molesworth,
672 A.2d at 616. We hold that even though a discharged at-will employee has no statutory claim for retaliatory discharge under
W.Va.Code,
5 — 11—9(7)(C) [1992] of the West Virginia Human Rights Act because his or her former employer was not employing twelve or more persons within the state at the time the acts giving rise to the alleged unlawful discriminatory practice were committed, as required by
W.Va.Code,
5 — 11— 3(d) [1994], the discharged employee may nevertheless maintain a common law claim for retaliatory discharge against the employer based on alleged sex discrimination or sexual harassment because sex discrimination and sexual harassment in employment contravene the public policy of this State articulated in the West Virginia Human Rights Act,
W.Va.Code,
5-11-1,
et seq.
IV.
CONCLUSION
In summary, we answer certified question one in the negative, as the period of time during which twelve or more employees must be employed by an employing entity under
W.Va.Code,
5-11-3(d) [1994] is
not
that period of time set forth in 42 U.S.C. § 2000e(b) (1991) (“for each working day in each of twenty or more calendar weeks in the current or preceding calendar year.”) We answer certified question two in the negative as well, because the Coalition, under the facts before us, is not an “employer” under
W.Va. Code,
5-11-3(d) [1992] because it was not employing twelve or more persons within the state at the time the acts giving rise to the alleged unlawful discriminatory practice were committed. As indicated in n. 12,
supra,
we decline to answer certified question three. Finally, we answer certified question four in the affirmative, as plaintiff may maintain a common law claim for retaliatory discharge based on alleged sex discrimination or sexual harassment because sex discrimination and sexual harassment violate this State’s public policy. Having answered the certified questions posed by the Circuit Court of Jefferson
County, this case is dismissed from the docket of this Court.
Certified questions answered; case dismissed.
