Imagine if you will that..

... You have a full time job that involves working mixed shifts. The job is safety critical, with potentially dire consequences if you make a mistake.

The company you work for says that it will pay you double time if you volunteer to work exrra hours on Sundays.

After a period of time, the company decides that it no longer wants to pay you as much in return for you volunteering to work on Sundays.

You decide that you would rather spend the time with you family and friends.

Now imagine that you are a driver working for London Midland.
