Harry is offered an annual salary of £1400 for his new job. This was rather less than twice the average wage in 1965, so not a fantastic sum for the danger involved.
After Palmer hurts his wrists in the first brain washing session, the next time he is taken his wrists are not injured. Even though it has only been two days according to the marks on the wall, and later they are hurt again.
