Hello, an employee of ours who has been paid overtime for four years has just been told that the policy has changed and he is no longer allowed to request overtime pay. In the past few years, he had flagged to the CEO on multiple occasions that he could not feasibly finish all the job requirements in his working hours due to the nature of the company's work and the CEO had told him to claim overtime as and when he needed it. My concern is that by suddenly changing the "policy" (and as far as I know, this isn't written anywhere), they have changed his financial and working circumstances without making any changes to the actual job responsibilities. I am worried that this is a breach of custom and practice and that he is being set up for failure by being told that he can no longer work overtime, but not making any changes to his role. Can anyone shed some light on the potential legal – and moral – implications of this?
