I have been working for a company for over 22 years, for the last 10 years I have been taking on extra responsibilty which was completely different to my contracted role.
These responsibilities were initially equal to 50-50 of my time but over the 10 years grew until all of my time was spent on the other role.
2 years ago, we were informed a merger with another company was taking place and various redundancies occurred. I was asked to continue the other role and offered a Secondment for 2 years as there was no-one else with the skills, however in the other company there was an unfilled, official post but a lower grade to myself. 8 months into the Secondment, I started maternity leave. With 8 months left on the Secondment I returned on a part time basis, the other post has been filled internally without advertisement (now the same grade) and my Secondment effectively terminated and I am now expected to return to my original role that I have not been doing at all for the last 3 years.
My question – is there any part of employment law that protects my role based on the responsibilities for the last 10 years rather than job title?
I do not want to return to my old role and would prefer redundancy.
Any advice would be appreciated.
