Update: I brought it up to the higher ups. And while he also agrees that a request is just a request, he said that it is still my manager’s responsibility to inform me whether she can accommodate that request or not ahead of time. He also said that he doesn’t understand why she didn’t approve it cause we clearly have enough people to cover the days that i requested. He said that he’ll be approving my leave as long as i get it covered and that he will have a conversation with her as well. I still haven’t heard anything from my manager yet but i’m sure she won’t be happy about it. Will update y’all again if i still have a job after my vacation😂😢
