Labour MEP Alex Mayer will pledge her support to a rally of McDonalds strikers on International Workers Day.
Workers voted by 95.2% for strike action at 5 McDonald’s stores across the UK.
The Bakers’ Union members are striking for £10 an hour, a choice of fixed hour contracts, the end of unequal pay for young workers, and for union recognition.
McDonald’s is the world’s second largest employer, with it's current chief executive Steve Easterbrook born and raised in Watford. Across Europe there have been protests to improve wages and end insecure employment in Belgium, Finland, France and Germany restaurants.
Ms Mayer said: “When it comes to rights at work McDonald’s workers are not “lovin’ it”. McDonalds responded to last year’s Cambridge strike by giving workers the biggest pay rise in a decade, but there is still more to do. Our message to McDonalds management is your burgers and fries would taste so much better if we knew the workers who prepared them were getting a fair deal.”
