Thanks for the advise so far everyone.
One thing was clear that they mentioned without prejudice.. this was an optional compromise agreement.
This is because they offered me a position to come back to, same pay and conditions but as I clearly explained to them in the back to work interview in Feb (!) , the role was not a good fit. They agreed.
They made an attempt to look for other roles, but none materialized. Then informed me that they are doing head count reviews and reducing contractors, and have made 2 redundancies. As HR put it, they had no other positions for me to consider at the moment unless someone resigned.
The way HR put it, 'Do I want to come back to the role on the table, knowing that all I want to focus on finding a different role?' And 'The person in the organization that does the role is need of a promotion and the can only promote that person if they have someone who could commit to the role' . Lots of in's and out's.
Lastly, I asked for flexibility in my return to work interview in Feb - and they declined stating that in this department, there is not anyone who could fill in/accommodate if I were away. Also starting earlier and finishing earlier would be outside of business hours- and I made an argument ie - I am on work BB/ able to WFH and on the go...
We're not manufacturing widgets- this a £17bn investment co.
Essentially the person in the role at present doesnt have a partner/children... just 100% committed to the company and the role all hours, any time of the day, even on holiday. Obviously I would never be able to commit to that.
They have offered me a recommended solicitor -(!) is that a bad thing? they will cover the first £500.
Also they mentioned some sort of help out of the door.. ie CV and interviewing help with another company?
