I just wonder if I should tell my manager that I want to quit in a few months from now or not. Below I am going to provide you with some context and description of my current situation.
Basically I am currently working as a Linux System Administrator/Infrastructure Administrator. In our team we have on-call rota which is one week long and also we have some tasks that we can do only after the office hours or even at weekends. The thing is, 2 guys quit, one in January and one in April this year, so we're kinda shorthanded.
Because of that, I feel overworked and overwhelmed by my responsibilities and sometimes I don't have enough time to do the things I need to do besides working (my goal is to learn cloud computing, a few new technologies and improve my spoken and written English because I want to move abroad). A few weeks ago I've had 3 weeks of on-call duty straight and I also worked all alone at that time because my only one teammate was unavailable.
The thing with my manager is, he gave us a raise, a massive one I would say, it's about like 50% of what I made before. That kinda feels like I got 50% of salary of that one dude that left us. That sort of feels like they predicted how I feel and they want to keep me aboard as long as possible. That haven't changed the fact that I'm dissatisfied with my job and it makes me miserable. Since May I have been taking part in various recruitment processes which gave me insight on what I should improve.
There was that situation recently when two guys from other team quit and my manager threw papers at them and said that they're not worth anything and he can replace them with anyone. That story made me think that this guy doesn't actually respect anyone at all.
That's about it. I don't know what should I do or even how soon I should quit. I haven't found a new job jet, but I'm saving money for doing courses and learning thing I need and want to learn.
I feel like this situation won't improve and I certainly want to quit. I just wonder if I should tell this guy I want to quit in a few months upfront when we're going to sign my new contract, give him some time to do something or just pretend to the end.
I have a gut feeling that no matter what I do, I will be the bad one but at least I posted here because I wanted to ask someone for insight.
EDIT: In case anyone's wondering what I did:
I haven't told my manager anything until I got a job offer from another company. After that I went on a 1v1 meeting with him and gave him my notice. We talked a bit about the company, technologies etc. and I'm currently leaving that sinking ship, after 31th October I'm going to start a new journey.
