I currently work part time 3 days a week managing a team of 11. I have been in the role for 14 years, working part time for 8 of those years. I easily do the equivalent of a full time role, working long days on the days I work, occasionally working on my days off, continually monitoring emails & have never had, to my knowledge, a situation where my working part time has negatively impacted my team who are all performing well.
We have recently got a new Director who wants me to increase my hours, she has said ideally 5 days but would settle for 4. I really do not want to increase my hours, I would struggle with existing commitments & am fortunate I don't need the extra money. Her argument is there needs to be cover at all times & has said she'll initiate a consultation. I'm possibly prepared to work a 4th day til school pick up time but don't believe this will be acceptable.
I've spoken to Acas so I know the facts, but I'm a bit lost on exactly how I should approach this, what I should say or what arguments I should make to get the best outcome. Or whether I should just suck it up & be grateful I have a job!
