So to cut a long story short I have recently received a pay rise for learning to run a machine. I have ran this machine with no extra pay occasionally for around 2 years. The other machine operatives where very supportive of me getting paid until I actually got paid and have now made comments along the line of why should I get paid when I'm just doing a general ops job. Which they also do occasionally for cover and still get their money. I will be more of cover for them and they all still make more money than me.
I will not be replacing any of them but whenever anyone tried to step up they try to put a stop to it stating their jobs are at risk....they're not. Aibu to not understand any of this?
