My company went through a restructure earlier this year. It was handled horribly, I was on mat leave at the time and they essentially told me I had to return from maternity leave early to competitively interview for 1 position against someone I previously managed. After speaking to ACAS and pregnant then screwed they conceded they couldn't do this and offered me another position. No longer a manager, two 'grades' lower, less pay and 4 days a week from full time. They continued to argue I wasn't part of the redundancy process as I had a position secured despite it being completely different to the role I held previously. Again not very willingly they conceded that I would be given 4 weeks to decide if the role was for me after returning where I could still take my redundancy payment if I didn't want to continue.
I stayed, my partners self employed and with two children under 3 and a new mortgage I needed a regular income. Now I'm working again I can see that my previous role has basically been divided up between the two managers in charge of the restructure and a third person, they have all retained some of my old responsibilities for themselves. There is a planned outsourcing of work which will affect my workload further and I can see there will be no need for me at some point in the near future. This was known (although not the full extent) when I accepted this new role but they advised my role would be transitioning into something different, which I can now see is not happening. My old duties are still needed after the outsourcing. Things I was told I'd be responsible for have gone elsewhere, I feel like this role was missold to me, it has no longevity. It's worth noting there were zero performance issues before maternity leave, if anything the opposite was true and I had received a pay rise and bonus for exceeding.
My questions are - if I were to be made redundant would it be based on my old pay and hours, or the new role with less pay and less hours even if only held for a few months?
Is there anything I should be doing to protect myself? I feel I have been stripped of everything I had worked hard for and placed in a 'made up' role as I called them out on their mishandling of the initial restructure.
