I am currently employed in a salary position. For over 4 years I have had the flexibility of choosing my work hours as well as my coworkers. I recently got a new supervisor and was informed by the interim supervisor (individually including someone from HR) that I had 2 weeks to change my hours. I was told that everyone would be expected to work the same hours. Since then there have only been 2 other coworkers that were informed of the new change. It has surpassed the 2 week window. There are approximately 30 coworkers this issue wasn't addressed with. Is this legal? I feel like I have been singled out and it doesn't seem fair. Many of the 30 are not working the new standard time nor were they before the change.
