I have accepted a job in the NHS. All the employment checks have been met, references, occupational health, starter forms etc but now the employer wants to change the term of the contract. I'm waiting on a call to find out the full scope of those changes. I'm anticipating a reduction in the hours, or a change to the days of working but I don't know for sure. I'm just wondering what rights I have. Does the employer have to honour the agreed hours and days of working, and the salary, once the job has been accepted, and all the checks met etc. I'm literally at the point in the process of arranging a start date. Do I have to accept any changes they want to make? Thanks in advance for any guidance given.
