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.

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.

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.

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 depressed and uninterested, and had difficulty sleeping, lack of appetite, concentration difficulties, and lack of energy. When she asked whether Milstead would like to return that day, he said his energy level was so low that he did not feel he would be able to work at that time. But, he said he felt he would be able to return to work in a couple of weeks. The administrator and Milstead discussed the possibility of Milstead spending that time obtaining more counseling and maybe altering his medications.
