My employer is starting a company wide consultation to change contracts for managers. Among other things this will mean losing premium rate pay for Sundays late nights and bank holidays and including a clause to say you'll have to work 3 in 4 Saturdays and 1 in 4 Sundays. I'm part time and only work the odd weekend (usually one Saturday a month, sometimes more depending on business needs) and am not happy about having to work the same number of weekend days as someone full time. Surely it should be pro rata? I will be seeking advice from my union but the company say they do not recognise unions for management, can this be right? Suppose I should be grateful to just have a job and will have to suck it up :(
