FAST-FOOD giant McDonald’s will be hit by a new wave of strike action tomorrow as workers walk out at its restaurants across the US to demand fair pay and trade-union rights.

Thousands of employees are expected to take part in the Fight for $15’s latest protest over three days.

The aim is to press politicians to take notice of their demands to raise the minimum wage for fast-food workers and others who are paid at the lowest rates.

They will be joined by care workers, professors and caretakers in seven states to walk out of restaurants, hospitals, universities and other establishments as part of a campaign prior to the US midterm elections.

The Fight for $15 campaign was established by the Service Employees International Union in 2012 to organise those in the fast-food industry and get better wages for them and other low-paid workers.

It claimed a victory today when online retail giant Amazon announced it would be paying staff a minimum of $15 per hour.

A Fight for $15 spokesman said: “Workers worldwide have been standing up, joining together, and winning. Amazon is just the latest company to respond. The Fight for $15 won’t stop until every worker has a living wage and unions for all.”

As part of tomorrow’s action, workers will be knocking on doors before the midterm elections to remind the public what is at stake in November’s poll.

Fight for $15 said in a statement: “To fight back and win we need politicians to change the rules, making it easier for workers to organise and join strong unions.

“Unions make it possible for all Americans to get ahead, not just the wealthy few.

“We’re launching a huge mobilisation to make it clear to every politician — either you stand with working people and support unions or you lose our vote. Period.”

Last month, McDonald’s was rocked by a strike related to allegations of sexual harassment in its US restaurants, which commentators branded the company’s “#MeToo moment.”

Those joining the protests alleged that they had been subjected to touching and even attempted rape by senior managers, which workers said was not taken seriously by McDonald’s.

The company responded by saying it has strong policies on sexual harassment but was working with external organisations to improve and adapt them as necessary.
