McDonald’s has launched a new investigation handling unit after the BBC reported on dozens of abuse allegations at the fast-food chain.

Alistair Macrow, chief executive of McDonald’s UK and Ireland, said the claims he had heard this week are “personally and professionally shocking”.

He apologised to anyone affected.

However, current and former workers that the BBC has spoken to said it’s “too little too late”.

A BBC investigation was told workers, some of them teenagers in their first jobs, are being groped and harassed almost routinely.

Mr Macrow said: “The unit will have oversight on all cases and the power to refer the most serious cases to a third-party legal team staffed by specialist investigators.

“The unit will be run by human resource and legal professionals full-time until at least the end of this year.”

As well as setting up the investigations unit, McDonald’s is appointing external experts to independently examine how workers’ claims are “escalated”. This can mean looking at when and how complaints are passed to other departments or more senior managers.
