Someone who knows more about employment law can advise you better than me, and I am not much help. But YANBU. I would be irked too.
I used to work for a big corporate employer and they were constantly sending me on fucking courses! Stupid pointless shit, like 'race awareness' 'equal opportunities' 'how to be more assertive' 'breaking through the glass ceiling' 'empowering women in the 21st century ' and other equally naff shit.
I lived and worked in the black country, and the courses were often in London, or Manchester, (No idea why!) and it took about THREE HOURS to get there and THREE HOURS to get back. Plus the 8 hours of the day there. Some courses were Monday to Friday. Five 14-hour days, and I never got paid any more for the 6 hours of travel. I only got the money back for the train and buses; about 6 weeks after I paid it!
I hated travelling to places and things I never wanted to go to, and it really stressed me out. Especially as the days were so long. One course leader let me leave an hour early (at 4pm) one day, as he knew I lived 100 miles away, and my manager heard about it (as someone grassed me up,) and he proper laid into me for leaving an hour early, saying 'these courses cost us £50 a day per person, you are basically robbing the company!' With this
look.
I said 'yeah but I am not even getting home til 8pm, and I am only paid til 5pm. 'I DO NOT CARE.' he snapped. Many many people have long commutes for work, why should you be any different?' 'I said 'I didn't even ask to go on the course.' Then I got a verbal warning for insubordination.
Cunt.
Didn't stay there much longer.
So yeah, YANBU for not wanting to go gallivanting up and down outside of the workplace!
