One of my colleagues has gone on leave following a bereavement- their loss has completely come out of the blue.. We're working on a project together atm and there's a deadline looming where the colleague is responsible for a piece of work that's due in in a fortnight. I supervise my colleague for a few bits and pieces and oversee their eventual work. I have no idea if colleague can get their work done while on leave- I doubt it and I wouldn't be able to if I was them. I approached our Manager asking if there was the possibility of an extension on the colleagues work. Manager has just come back saying no- she doesn't care and wants the work done. Manager has been a complete bitch towards me and others in the team in the past. I want to send an email back pointing out her callousness but don't know how to word it without coming across too emotional. I won't be able to do my colleagues work since they've already carried out a lot of work on the bit of project they were involved in and I don't have the time to pick it up. Can anyone help me?
