you don't even need cover if your timeline is not artificially short aka calculated by working 14 hours per day to make it in time. if there's buffer, just come back after MC to do... or be chill enough that I had time to teach my teammate to do the same thing I do beforehand.

that's why your IT maintenance always ask for 7 days when the actual task is just 2-4 days.

but at the end of the day, this is a partner problem. audit partners are not resourceful and lousy at problem solving. this is why you see so many lawyers, businessmen, bankers as ministers but not auditor.
