There is a different option available at Gatwick...instead of working for free we are getting offered £80-100 to come in on our days off to do overtime because someone somewhere has cocked up the manpower figures...AGAIN!!
Not necessarily. It's generally cheaper to pay overtime than it is to employ extra man power (no NI or pension contributions for example). I'm sure you could volunteer to work for free if you really wanted to and save the company £80 - 100 per day.
