UberEats riders and a small number of workers from JD Wetherspoon, McDonald's and TGI Fridays are striking over pay...Walkouts will be held in several UK cities, along with a rally in London.The industrial action is being taken in tandem with strikes by fast food workers on four continents. UberEats, JD Wetherspoon and McDonald's have defended their record on pay, while TGI Fridays had no immediate comment...McDonald's said support for the union among its staff was "diminishing" and "any suggestion that this activity is widespread and growing is not accurate". JD Wetherspoon has previously said it had announced pay rises worth £20m last year and £27m for this year...TUC general secretary Frances O'Grady told the BBC's Today programme that the strike was "small but growing". She said some modern hospitality employers and technology firms were "using a very old form of exploitation".
