how awful for you hun. I think you have been given heaps of awesome advice. As much as it would be tempting to go in guns blazing I wouldn't give him one INCH to use against you. I would go in, disagree with everything he comes up with, definitely let him know you are taking things further as you see it totally as discrimination even if that is all you say today. Keep it simple, let him talk and dig himself a hole - agree to absolutely nothing until you have sought further legal advice and leave it at that. You don't want him to say you are argumentative and further offend him by talking about the lack of staff respect for him as it really doesn't have anything to do with your situation in him decreasing your hours etc. good luck hun, really tricky but I hope you can show him you won't back down, that he is totally in the wrong and prove him wrong in that you can do your job well, and being pg doesn't change a thing.
