On Appeal from the 477th District Court Denton County, Texas1 Trial Court No. 22-2726-211, Honorable Michael Dickens, Presiding

June 11, 2026 MEMORANDUM OPINION Before PARKER, C.J., and YARBROUGH and PRATT, JJ.

Appellants, Jennifer Nelsen and Terri Steigleder, heirs to the estate of Jon Tillman

Milstead (“Milstead”), appeal from the trial court’s ordering granting summary judgment in

favor of Appellees, Denton County, Texas, Denton County Sheriff’s Office, and Tracy

1 Because this matter was transferred from the Second Court of Appeals, we apply its precedent

when it conflicts with that of the Seventh Court of Appeals. TEX. R. APP. P. 41.3. Murphree (“Denton County”). Milstead challenges the court’s order through four issues.

We affirm.

BACKGROUND

Jon Milstead suffered from chronic migraines beginning in 2002. He lost his sister

in 2008. He married his wife in 2016. His wife had a brain tumor and passed not long

after she and Milstead married. A year later, his mother-in-law died from the same cancer

suffered by his wife. Milstead was diagnosed with depression and post-traumatic stress

disorder following those events.

Milstead’s law enforcement career began when he started working as a jail

detention officer in 2014. He obtained his peace officer license in 2017 and began field

officer training in 2018 with the Denton County Sheriff’s Office. Milstead took FMLA leave

from July 17, 2018 through August 3, 2018, for medical issues. Not long into his training,

Milstead moved laterally from Deputy Patrol to Background Investigator of the Denton

County Sheriff’s Office, effective December 1, 2018.

In 2019, Milstead was promoted to Investigator-Professional Standards Unit in the

Sheriff’s Support Services Division. In this position, Milstead was responsible for

conducting background investigations for both internal and external job applicants. His

supervisor, Captain Kelly Fair, favorably evaluated Milstead, noting he was “quick to

learn” the position, wrote his reports well such that they were rarely returned, and was a

“true team player.” Kelly even recommended that Milstead pursue his college degree to

benefit his growth with the department.

2 In early September 2020, Milstead talked to Sergeant Jimmy Lewis and Captain

Fair about his migraines and depression. He indicated he planned to seek help from his

doctor. A few weeks later, on September 23, 2020, Milstead told Fair and Lewis that his

doctor was recommending he take time off work. Fair provided him the necessary

paperwork, including a document requiring that Milstead and his doctor provide a

description of the relevant medical facts, an estimated treatment schedule, and an

estimate of the period of leave needed (Certification of Health Care Provider for

Employee’s Serious Health Condition).

Milstead completed his paperwork and took time off from September 24 to October

5, 2020. He returned to work in early October. He took emergency sick leave from

October 21 through October 27, 2020. On November 10, while Milstead was driving to a

doctor’s appointment, he called Lewis about getting help. Later that day, Milstead told

Lewis he would be in the hospital for inpatient care. Fair filled out a notification for

Milstead with an “unknown” anticipated return date.

On November 16, Milstead returned the FMLA certification form to the department

for his leave, indicating leave was necessary for “major depressive disorder, recurrent,

severe, without psychotic features.” His doctor stated the condition would cause “episodic

flare-ups” that would periodically prevent Milstead from performing his job functions. The

doctor recommended that Milstead participate in a partial hospitalization program for

about two weeks. This leave was approved, with an anticipated date to return to work at

the end of November 2020.

3 On November 23, 2020, Milstead’s physician sent Denton County a new FMLA

certification, extending the estimated FMLA leave through February 19, 2021. This leave

was apparently necessary to attend medication and therapy appointments twice per week

as part of an intensive outpatient program. The doctor noted that Milstead’s symptoms

of depression were interfering with his ability to perform daily living tasks. The FMLA

leave was approved with the notation that Milstead would exhaust all of his FMLA leave

hours on February 15, 2021. On December 23, 2020, Milstead successfully completed

the intensive outpatient program, and he was released to work without restrictions on

December 28, 2020, in advance of the expiration of his FMLA hours.

However, Milstead did not return to work until January 7, 2021, due to exposure to

COVID-19. Denton County designated Milstead’s leave due to COVID-19 as FMLA

leave, not FFCRA (Families First Coronavirus Response Act) or sick leave under Denton

County’s sick leave pool policy. 2 As a result, Milstead was not paid since the FMLA leave

was unpaid.

On November 5, 2020, not long after Milstead’s first FMLA leave, Lewis alleged

that Milstead interfered in Milstead’s father’s background investigation. He gave Milstead

a verbal warning and told him to refrain from interfering in investigations in which he had

a personal interest so that the investigator could complete the investigation without input

or personal bias. When Milstead returned to work on January 7, 2021, he learned his

father’s employment with the sheriff’s office had been denied. He made some inquiries

2 Tony Luton, the new Assistant Director of Human Resources, concluded that Milstead’s major

depressive disorder did not meet the definition of “catastrophic illness” and therefore, determined Milstead did not qualify for leave under the sick leave pool policy. Denton County denied Milstead’s request to be paid from December 3 to December 23, 2020.

4 concerning the denial. On January 22, 2021, Fair placed Milstead on an Internal Affairs

investigation, alleging seven policy violations related to Milstead’s queries concerning his

father’s employment. Fair administered a warning to him and placed him on indefinite

administrative leave. Milstead contacted a medical provider, indicating that the

administrative leave situation was causing him stress and confusion and his migraines

had returned. The doctor recommended he follow his medication routine and follow up

in two months.

In February 2021, Denton County notified Milstead that he needed to perform a

fitness-for-duty evaluation. Fair requested the evaluation based on her observations of

Milstead’s appearance, work performance, anger issues, and general unusual behavior.

Milstead attended the required psychological evaluation on March 29, 2021, while he was

on paid administrative leave. The administrator of the test found Milstead’s mental status

was in the normal range. His aggression scores were within normal limits, and he was

comfortable in social situations; he was friendly and extroverted. Milstead tested low on

the suicidal behaviors test. Milstead did tell the administrator he had been feeling
