My Job Told Me That "acting Manager" Means I Do Not Get Overtime. I Am An Hourly Employee.

Location: Texas

Long story short. My job let go of several VPs. We went from over 80 VPs org wide down to 50ish middle of september. Including my DIrect VP. My manager is now a vp, at much lower payscale than the person he replaced mind you, and I have been asked to step up as acting manager.

Over the last two weeks I have accrued roughly 20 hours of overtime which my job is trying to screw me out of.

There is a culture of "Fix it now!" at the company that is both stupid and unprofessional. A sales person is trying to push paperwork out at 3 AM, which they should have done at 3 PM, but the server is giving errors? Better call the IT On-Call. Which is just me now. We cant have a sales person being forced to wait until tomorrow morning to get this paperwork done. Otherwise they complain to the wrong people and I get that call.

Per company handbook the minimum time you can list is 30 minutes. Meaning if something takes 5 minutes, I get a half hour. Now if someone calls me at 9:05 pm, I get it done at 9:07 and I get another call at 9:15 and get that done at 9:20, thats still only 30 minutes.

I havent been cheating the system. I legit have been accruing 10ish hours of overtime each week over the last two weeks.

I received an email this morning from some EVP, who is not over me in the org chart, asking me to stop logging overtime as I am an acting manager which means I am not eligible for overtime.

Im pretty sure they cant do that, but just figured I post here to check. My VP already approved my hours this pay period. Does being an acting manager change my legal status as an hourly employee? Or is this just another corporate manglement situation?
