DH has worked for his employer for more than 2 years. He has fixed hours stated in his contract. After a few months he suggested that work pattern B (shifting his hours slightly earlier) would be more helpful. That was accepted.
Over the last few years his employer has required him to change his work hours 4 times because other staff made requests that would require him to change his hours. It has always been presented as 'fait accompli' and he's been told, essentially, not to rock the boat because if x leaves they won't be replaced.
Then, he was told that a certain event had been arranged on a regular basis on his non-working day, but he was required to take turns in accommodating the event. Sometimes this involves popping over at the start and finish, other times it requires a whole day of attendance. Then, it turned out that nobody else on his team was willing to stay if the whole day is required, so it fell to him.
He is far too nice and has accepted all of this.
Now, the organisation needs to save money, so they are stopping one job role, and changing his role. He has so far been told that it will likely involve a change of hours, but no details are yet available of the scope of the job description or the pay. Given that they need to save money, I can only presume the pay for the new role will be lower.
His manager has said it won't be a redundancy situation as another role is being offered. I'm not sure this is true.
