In October last year I prescheduled a vacation for the month of July. At the beginning of July I asked when the week of my vacation begins, and my manager constantly put off telling me. Last week I was still working and I had to go get tested for Covid. Well while I was in quarantine, I had to repeatedly text when my scheduled vacation began. Still no reply. So after testing negative today. I had to drive to the hub and they told me my vacation was last week. They had failed to tell me when I first asked and they counted my quarantine as my vacation. Which I did not request to be done. What the am I supposed to do? They failed to tell me and now my prescheduled vacation is ruined. My manager has constantly failed to do the right things but this was the final straw. Are their grievances or actions I can take?
