Currently having new computer system installed. Colleagues are working on the new system so I'm currently covering for 3 others- working through lunch and putting about 2 extra hours in per week (7hours extra per week in total)
We have now been told we need to work an extra 5-10 hours a week to learn the system and in exchange get the change to win a £20 amazon gift card.
Can they do this? Or do I have any rights to say no? Thanks
