My team is Team Y and we sit in dept Z.
A colleague in dept Z is going on leave for 2.5 weeks during Easter. The head of dept Z, my manager’s manager, has asked me to cover the colleague’s work. I said yes but after speaking to the colleague, I realised the bulk of the work would be during the Easter half term break. I had planned to take 4-5 days off during April to look after my children.
Would it be reasonable to ask my manager for someone else to be assigned to help me and cover for the days when I am on leave.
My team is very understaffed. Two people have left in the past month so everyone is extremely overworked.
