Serving caviar at up to £200, Harrods’ array of restaurants are among of London’s most expensive department store eateries. So when it comes to handing out the tips to staff, you would be forgiven for thinking that the famous Knightsbridge store would be among the most generous companies to work for. But workers at its 16 restaurants and cafes have launched an attack on their bosses, claiming that the company keeps up to 75 percent of the service charge on each bill. United Voices of the World, the union which represents waiters and kitchen staff at Harrods, has called on workers to protest outside the store on Saturday over the situation. It says the current system means staff are missing out on up to £5,000 a year. A social media posting promoting the demonstration said, “One of the wealthiest stores in the world is withholding tips from the low-paid staff in its restaurants. Harrods keep up to 75 percent – that’s around £5,000 from each member of staff. No more! A 100 percent of the service charge must go to the workers.” It is thought that there are 483 members of kitchen and waiting staff working in the store’s restaurants and cafes. UVW General Secretary Petros Elia, said, “Customers expect the service charge to go to staff and that’s where it should go. If Harrods feels the need to retain a percentage they should explain why.” A spokesperson for Harrods told the Guardian that the company operated a ‘tronc’ system in which the service charge is only shared out among the staff who has accepted a cut in basic pay. “Harrods is taking steps to improve the current system through which it distributes its service charge, to ensure it best serves our employees and is completing a detailed review into the existing scheme,” she said. “As this is an ongoing review, we are unable to provide further details on the distribution. However, employees will be informed of the details of the new system as soon as the review is complete.” Controversy over staff not being paid service charge hit the headlines again last month after celebrity chef, Michel Roux Jr admitted that he keeps the payments £212-a-head Michelin-starred Le Gavroche restaurant in London.
