I am a salary worker and don’t get overtime since we don’t track our hours. Today I let my job know I will have a upcoming appointment and would need to leave 4 hrs early from the 10hr work day so I would be working for more than half the day. I let them know the hours would be made up during this week and would be able to work all 40 hrs. They informed me this time it would be ok but next time I would be forced to use my PTO. I feel like the is unfair as I can be asked to work overtime without compensation for the extra hours, which I’ve done, but I can’t work a few less hours without being forced to use my PTO. Something doesn’t seem right, is this allowed?
