I will be OOF for Few Days and Mr.X Would Handle Everything Till I Return

I will be Out of office for few days. Mr.X would handle everything in this project, till I return.

Mr.X would be in the most pathetic situation till, his manager returns. Because, whenever the manager goes on leave, he/she would give responsibility to one reportee of him/her. But, most of the time, the reportee won't get any power in taking any decisions. But, they have all the responsibility to solve the problem. Most importantly, the reportee cannot take the decision of "Not solving the problem", whereas the manager can take.

If the peers of the manager have issues with the manager and/or the reportee, then the reportee will have very good time when his/her manager is Out of office, and he/she gets the responsibility.
