I started my job 10 years ago.
About 5 years ago, I was asked to do a task that takes about 6 hours a week. It is different to my main job, and involves a mentoring scheme for diversity entrants to the field.
This is a prestigious project for the company, and due to the hard work and dedication of the 4 team members (including me), the project is now a regular programme that we offer.
I have been told that I have to continue with this work, but won't be paid for it, I.e. I have to work my full hours (35h) doing my "normal" job and the mentoring hours are on top. But I am only paid for 35h (no pay rise).
Is this a change to my T&Cs? After 5 years of being paid to do the mentoring? The company is very keen for the programme to continue, they just want it for free.
Can I object? Can I refuse to do the unpaid work? I actually want to do the mentoring.
