I am in condition that I and my colleague have some deadline.
When I asked him which task he wanted to do (task A or B), he answered he wanted to do task B. Task A is on deadline two days from today and it need some days to finish.
Then in the midst of I am doing task A, he suddenly showed me he was on doing task A, so I switched our task. Up to this position, I was doing task B and he was doing task A.
Two days ago, my manager said to me (my colleague wasn't there) that the deadline of task A will be 3 days from today. Then, on afternoon, my colleague, suddenly (again) he sent me email. Following are the important points:
- He confused on doing task A
- He said if there are something lacks on it, it's up to me to modify
- If there are things in task A that may can be considered impossible to be done in future, he said it's up to me to change whole task.
At this point, he really fed me up since I have trusted him to do task A (in his own initiative anyway), but he sent me that email and that deadline is 3 days from today (since 2 days ago upto today I couldn't do task A because I am on deadline of task B).
How to react to this situation? Should I tell my manager about this condition? Is it ethical in work life?
