I will be going part-time (0.6) in September. One of the first two CPD days falls on one of my days off. I have told the school that I would like to attend the CPD day but that I would also like to be paid for it. They have said that they do not pay additional hours for CPD days for any part time staff but that I can attend and have the time off some other time to be agreed with my HoD. Is there some way to challenge this? Getting the time off any some other time seems like a non-starter as it would mean missing lessons, which I don't see as acceptable. Does this mean that I just have to accept missing the first day back when there will be departmental meetings and lots of catching up and analysis unless I do it unpaid? This is my first part-time post - is this situation the norm? If it helps, I am the only part-time member of my department. Thank you.
