I am relatively new at a company (< 3 months) and am working in a development capacity. Despite the current climate, I still would like vacation time even if that means sitting at home. I am however encountering an issue with my requests not being approved on time by my manager, let's call him Jon. The company guidance regarding notice is usually double the amount of vacation requested (e.g. You want one day off, you must request the leave two days in advance).
I have requested vacation through our HR system twice now and it has never been approved in time. On both occasions I supplied plenty of notice (1+ week notice for 2 days off) and sent a couple of emails and IM's to Jon but never received a reply. This resulted in me cancelling my leave in both instances. I was slightly irritated it had come to that since I had followed protocol.
I am aware Jon is a busy person and perhaps doesnt have that much time to be approving vacations but at the same time, I would like some time off. How can I approach this situation in the future? I dont want to just take unapproved vacation time and come back to a disciplinary.
