"The significance of mutuality (of obligations) is that it determines whether there is a contract in existence at all."
"Did the first respondent treat the claimant as an employee? He was not recorded on their database as such. He did not receive induction training as an employee and he was not in the NHS Pension Plan. On the other hand they clearly expected him to attend work on a regular basis. As Mr Gregg [of short term] put it so succinctly no one asked him if he would come into work, he simply continued to do so because he expected and was expected to go into work. To that extent that demonstrates there was mutuality of obligation."
