If you find out that someone is in breach of employment law - making staff work for 2 weeks without a day off for example - what can/should you do about it?
If you only have the word of said staff to go on, and you know that they are too afraid to "push their luck" because they are non-nationals in fear of losing their job in this economy? You hear that they have said to their employer that they are too tired to work 12, 14, 15 days in a row without a break and they would like to work only 6 days in row, then one day off - and the eyebrows are raised, the question is asked how much they value their job...
They are a victim of their own tiny wage with a family to support.
What would you do?
