I have a colleague who has recently been choosing to do work that is not deadline driven neither is it of high priority. There is other work that will probably get us more attention and visibility to our seniors and they choose to do that work.
Whereas they know very well that as a team we have tasks on our plate that have hard deadlines as opposed to the task they are doing that is still 1 week away.
My colleague is the same designation / role as me in the team and ideally it would be great if we could sync up between ourselves to complete deadline driven chunks of work before looking at other work. But my colleague was caught today in their own words and I realized that they is not intending to help me but rather do work that will get them more visibility in the company. If I had the time too, I'd also like to plunge into the other better work.
How do I deal with this person? I have already told her that if there is time, they should first pick up the higher priority work first and then we both can dive into the other work together.
