I'm livid. I work 4 days a week, senior role. The project has been given to someone else on my team as it's closer to what they are already working on (fair enough, no problem) but also because I work part time (4 days a week, inc Fridays to ensure I am around for problems that crop up at the end of the week) and they are concerned I wouldn't be available when needed, running up to the project launch. They didn't bother to ask me how I would ensure cover was in place if I kept the project. I'm gobsmacked.
