I will probably start a new job on Monday. During my work interview they told me that I would be temporary, and that they would employ me through an HR company, which is fine by me. I asked them about the salary, which was "X".
Today I got a phone call from the HR company which told me that the company was interested in employing me and told me that the salary was "Y", which is lower than "X". I wasn't comfortable on talking about the numbers on the phone and told "Okay, let's discuss this further on Friday, when I come to sign the contract."
My question is: should I accept "Y" because it's the HR company who gives me the salary (which is still higher then what I get at the moment) or should I try to negotiate?
Thanks for your answers
