I work in a finance role, involved in the opening of new supermarkets. Roughly 2 years ago a new Project Manager joined the team who is responsible for coordinating the whole process of opening the new supermarkets. She joined the team from another department within the company so already had useful knowledge and skills.
At the beginning I tried my best to help her. I answered all the questions she asked me to the best of my ability even if it wasn't area, I directed her to the correct department when I couldn't help her etc. I just tried to be a welcoming and supportive colleague and help wherever I could. However it quickly became clear that within her department of Project Mangers she wanted to give the impression that she had hit the ground running and didn't want to ask her boss or any of the other project managers whenever she had doubts about anything, everything came straight to me even things not remotely related to finance. After a year I did start replying to a lot of her questions that these are things she needs to ask her boss or more experienced PMs and that has died down now.
Unfortunately this person is not at all suited to the job of project manager as they are extremely unorganised and forgetful. Until recently I was always sending her reminders about information she needed to send me, things she still needed to follow up on etc. but after 2 years it was really starting to get on my nerves that she still hadn't got the hang of the job and I decided to stop. In my opinion she should know all of this by now and be able to deal with the projects on her own. Me supporting her wasn't doing her any favours as no one was picking up that she needs help. Her manager was only really concerned about getting openings done on time and as long as that was achieved no one was looking at what this colleague is doing.
Things are now going downhill for this colleague and although she hadn't said anything I can tell that she is resentful of me working with her is getting uncomfortable.
Would other people have continued to support the colleague? I do feel a bit bad but equally I have enough on my plate and she has enough people within her own department who she can turn to for help if she needs it.
