Without giving too much info that could give me away in RL here are the details.
When I left for maternity leave my then manager also left at the same time for a new role.
Role on 12 months, the company has restructured and I return to find I am now managed by a colleague who was previously on the same level as me and that all my old peers are slotted into new roles.
My first day back coincides with a company event where my new manager gets drunk and tells me to forget about my old job as it's gone and that i'll be doing something completely different for him in not a particularly nice way. Fair enough, I took the full year off and can't expect to come back to exactly the same position.
However, it quickly becomes clear that my new job is effectively a demotion and that I am on a similar level to someone who reporting into me before I left on mat leave.
I stick it out for a while but when I find myself in the same room as someone from the HR team I tell her the situation. She is very supportive and offers to speak to my manager's boss which I ask her not to do for the moment as they have a close relationship and I wanted to think about it further.
It is then announced that the company is going through another restructure and senior roles are recruited. I assume the next tier of roles are going to become available further down the line but this doesn't happen.
With nothing to lose, I go to the group head with my CV and job description from my previous role and let her know the sort of role I would like and where my skills lie. A couple of weeks pass then I get a call from her asking me to go full time (I work 4 days a week typically) to oversee a couple of projects. I agree and complete the work. I'm on holiday for a couple of weeks and return to an email saying that I will now report into her going forward. I have been doing this for a few months now and have informed HR that I am much happier in this new role.
It's worth mentioning that I have not had a new job description since I've been back either in this role or the one I came back to, or appraisal.
It looks like the company is reducing head count and that I am very much at risk as I don't actually have a recognised job within the company and haven't since my maternity leave.
Do I have any recourse should I be made redundant?
Apologies that this is so long!
