Ooohh DaisyLily, I really sympathise with you and wish I had some good advice to help you out. Is there any way you could approach one of the bosses and speak to them in confidence to see if you can gain their support. If things really are that desperate maybe you should think of putting in a complaint. If you don't get on with these girls and they are making your life a misery then perhaps you have nothing to lose and everything to gain? Sending you a supportive hug x
