Retail giant Marks & Spencer (M&S) has been warned that it may face legal action if it contravenes employment law concerning redundancies.
Following a recently released Christmas trading report, speculation emerged that the chain would announce it is to axe 1,000 jobs across the UK.
Following this, an employee at an M&S branch in Aberdeen claimed that she and two of her colleagues had been told they are to lose their jobs, while a part-time worker in London said she was told her job was ending this week.
According to the GMB, the firm could face a wave of employment tribunal cases if it announces a huge number of redundancies.
Legal officer at the organisation Maria Ludkin said: "If M&S tries to take a short cut and treat each shop as a separate workplace and thereby give only 30 days' notice, [the] GMB will not hesitate to take employment tribunal cases for a 90-day protective award."
One of the country's largest retailers, M&S employs more than 75,000 people in the UK and abroad.
