Some of this is really egregious. The top firms on this list shorted their workers by over £1,000. That's not pocket change. It's almost enough to buy four burgers and a milkshake at Five Guys.

This, however, is music to my ears:

More than 600 employers were ordered to pay affected workers the outstanding wages, with £4m returned to workers, according to the Department for Business and Trade.

The firms have also been issued penalties worth £7m.
