So my contract states that I am paid £16 per hour, and that it is for 5 hours a day, presumable because I do 5 x 1 hours lessons, or 6 x 50mins. But I'm also asked to come in for 8:50 until 3:20 which totals 6.5 hours. And I've been asked to do Form registration. It seems unethical to be paid for 5 hours when I'm on site for 6.5. It includes breaks and lunchtime. Some of that time I am using to check what I need to know for the lesson, so most of the time I feel I make a significant contribution. Is this yet another means of exploitation? (Sorry to sound cynical, but I thought exploitation went out last century).
