tupe is for when new companies take over and ya have a new employer
then what they do is offer a pay rise of a smal tiny ammount and ya sig a contract that then turns ya holidays half, wok bank holidays for same money and ll other crap like that
they tried that when i was a traffic warden and they offerd me a extra 30p per hour, then after 6 months all the silly fookers that signed a contract stating they hve to work 3 different shifts that finish as late as 10pm now have to work till 10pm
even though they was told at the time the companies contract is the same for all contracts they have, hence the 10pm finishing time
me and me mate never signed it as we didnt trust the whole " dont worry that will never be a thing where planning to do " we was told off our duty managers
good luck and keep us informed in what happens
