Trade unions formally accused McDonald's of breaching international labor standards by failing to address sexual harassment issues across its UK restaurants.
The complaint follows a BBC investigation. It highlights allegations of repeated abuse involving staff, including many teenagers.
An independent UK government body has now agreed to facilitate mediation between the unions and the fast-food company.
This development places renewed scrutiny on McDonald's procedures for safeguarding younger employees and managing complaints. It also highlights systemic cultural issues within its large, franchised workforce.
