If staff who regularly work unpaid overtime did all their extra hours from the start of the year they would not get paid until 1 March 2013. The Trades Union Congress (TUC) has named this day Work Your Proper Hours Day to celebrate their hard work.
Now in its ninth year, Work Your Proper Hours Day is a light-hearted campaign that celebrates the unsung - and unrewarded - hours that staff put in to help their employer and boost the UK economy.
On 1 March, the TUC will be urging bosses to let their staff take a proper lunch hour and leave work on time, and to lead by example by working their proper hours too.
Last year, the TUC found that employees across the UK worked nearly two billion unpaid hours, worth over £29 billion to the economy.
This year Work Your Proper Hours Day will look at whether the amount of unpaid hours worked has risen or fallen in recent years, as well as which jobs and regions of the UK do the most unpaid overtime.
