Dear Boss, no, i cannot squeeze one more thing in. We are down 80% of our team, and all the work is falling to me. I'm only here 3 days a week and I'm doing the work of 4 people. you do the maths. I'm not running your stinking event in June, I will be 7 months pregnant and about to go on (if not already on) maternity leave. I'm not running it, end of story. you will not be the cause of a work-related nervous breakdown, I refuse to let you be.
