Differences: I’m not a developer. I don’t do overtimes (if I work extra hours, I have to compensate them in the same month). Managers of different projects can’t agree between themselves on whose task is more important (predominantly because they are not in the same office).
I was hired by a company as a part-timer for project A. I was promised a full-time position as soon as the project size increases, which was supposed to happen in a few months. However it never did and since there wasn’t enough work for me as a full-timer, I started to look for other jobs. At that time, the company was looking for part-timers for project B and project C and they offered the positions to me. So now I’m a full-timer who works as three part-timers on three totally different projects. I’m supposed to allocate 25 % of my time to A, 25 % to B and 50 % to C. My line manager leads project D and she assigned me to help her with activity D1 (most likely because I sit close to her team). LM also assigns me to help other people with their projects from time to time.
Projects have different deadlines and requirements. Project A has deadline in the middle of a month, activity D1 needs to be done at the end of a month, other projects don’t have fixed (monthly) deadlines, tasks have various extents and can come anytime from different sources (from my office, from other offices inside or outside my country). They often do and I feel overwhelmed by them. Then I feel guilty because I can’t help everybody. I theoretically know which project is more important and LM says I can adjust allocated percentages when needed (but she is not happy when I increase percentage for project B).
I’m under this LM because when I started working for the company, I didn’t fit into any other team (even though I might be doing some tasks for them now). There’s also other thing – she’s going on maternity leave soon and has already found a new manager for team D but not for me (I can’t be under the new person). I feel like I don't belong anywhere.
How can I learn to prioritize my tasks? How to postpone less important tasks without feeling guilty and stressed by the people who assigned them?
