The TUC has calculated that 5.24 million people across the UK worked unpaid overtime in 2008 - the highest number since records began in 1992. The previous record was five million in 2001.
Employees who work unpaid would receive an extra £5,139 a year if they were paid for the additional hours they are putting in. The average amount of unpaid overtime is seven hours and six minutes - the same amount as last year.
