EPD says it all started back in September, when Officer Kathy Winters did not participate in three in-service training sessions.
Winters was excused from the fitness test session for health reasons, but the other two sessions were mandatory.
Officials say they became concerned the 21-year-veteren may not be fit to serve, so they put her on administrative leave with pay until she provided a physical showing she was fit for the job.
Winters was working an off-duty security detail, when her superior tried to serve her the order. EPD says performing security duties is not allowed when an officer is on administrative leave.
The department gave winters a written reprimand, saying she was insubordinate because she disobeyed her superior.
On Monday, the Police Merit Commission overturned that reprimand, meaning Winters can continue her duties without punishment.
