Thanks both for your posts - definitely things to consider there.

I have my annual review on the 19th, so I'll try and combine all the things you've suggested to allow me to broach the subject with my Boss.

You both have very interesting perspectives (thank you!) - I like the idea that it's appreciation.  That said, I have decided that I will request to use all of my holiday allowance and overtime to attend the course, or worst case scenario,  for my hours to be reduced by one day per week.

Unfortunately the attitude has made me consider all of my options, and even the possibility of transfering to another department.  I guess it's a case of 'whatever will be, will be'.

Good old Doris Day!
