If you are still subbing for them, raise you rate. IBM was one of my best paying contracts, but I hated the work. I kept raising my rate to make them go away, Finally I had to say you guys are eating up all my consultancy time, I can't take contracts from you, because I am becoming too dependent financially on a single source of revenue. It was a hard financial pill to swallow, given that I was making 4x my rate of any other contracts. We parted ways amicably but I had to make the break, as I was just becoming a satellite around IBM.
