I have been having trouble solving a task that has been assigned to me. My manager recently left for a two week holiday, but before leaving he gave instruction for myself and my coworker try to sit together and see if we can get past the problem. And if we were unable to then just to leave the task.
I did request that my coworker sit and help me solve the problem, but he told he had things to do which are more urgent, we will do it on another day.
Since then any time I bring up the subject my coworker just brushes me off, and finally pushed it to Thursday. How can I address this issue in the most professional and productive manner? Should I just send an Email to my manager informing him we did not have time to meet to solve the issue?
Side note : My manager is unhappy with me on this matter and my coworker is of the opinion that the issue lies in my work and that I should be able to solve it myself.
