the company i work for have had our division up for sale since september a deal for which fell through last month .on january 1st we were awarded a 2% pay rise across the company (lucky us you say ) well no as those of us who work for the division that is up for sale are not getting this rise till either the sale goes through (then at the discretion of the new owners ) or we are made redundant and the division closed down .what i would like to know is where do we stand legaly if this process drag on for two or three months can we insist that we get this rise ?
just make sure your accrued years go from the old to the new company as it could be a way of getting out of paying redundancy payments 
I think you should get the raise then if/when the company is taken over then all rights and conditions are TUPE’d over.
