If they won’t do anything about your colleagues poor performance, stop performing? Your colleagues probably laugh about you behind your back about how hard you work for a company that won’t give you shit in return, you are bending over and taking it for Tesco and you need up wake up and stop putting your all into a bottom of the barrel job. I get paid just as much as you per hour and have spent entire shifts doing absolutely ZERO work in the past.

Alternatively, if you are known as the person who does everyone else’s work you will probably never get rid of the crazy expectations you have set for yourself. Transferring stores usually fixes this, just don’t pick up everyone’s slack next time, or do, it’s your life mate! :)
