National officer Rob MacGregor said: "Our message to RBS is that if it wants to deliver on that commitment then it needs all its staff and they need to be treated with respect, rather than being used as disposable pawns." Mr Gray said staff deserved more. "If this speculation is correct then we need to know where the job losses will come from, how many workers in Scotland will be affected and what support packages will be put in place by the company to help those facing redundancy," he said. A spokesman for RBS last night said the bank would not comment on speculation. l Royal Bank of Scotland banking group customers will be able to use Post Office branches to place deposits into their accounts from later this year. Personal and business customers of RBS as well as its sister banks NatWest and Ulster Bank will be able to pay in cheques or cash in any of the Post Office's 11,500 branches.
