what the firm should do is say if all them jobs are the exact same they can swap them round sos any day you wouldnt know if youd be sittin on your hole doin the beep beep or youd have to put in a days work in the warehouse!!!!Courts can't do that. Only the market can do that.
If check out chicks want a storehouse wage, then go get a storehouse job. Yet more whinging and moaning and gimme gimme gimme.
If you want the pay do the job, or STFU.
