Work ethics is a fortnightly feature in Guardian Work where a reader submits a workplace dilemma and asks for your help. A selection of the best answers will appear in Saturday's paper. (And if you have a dilemma you'd like to share, anonymously, with our readers, please email us.)
This week's question
I work part-time but have recently enrolled on an evening course unrelated to my work. My boss often asks me to work extra hours which, in the future, might clash with my course. I don't want to say no because my boss might think I'm not committed, but I have paid over £200 for the course. What should I say?
What are your thoughts?
