Legal Advice Needed Urgently - possibly being screwed over by HR!

So basically make some positions redundant, give them new titles and slowly wait until people leave (assuming they have no rights) before employing new staff for less.

Were consultants brought in for this exercise?

I think they're using the restructure as a means to sidelining and removing unwanted staff without having to go through proper redundancy stuff.
Not sure if I'm unwanted but they don't want me in the role for which I was employed.
