The National Union of Public Workers (NUPW) is threatening protest action on behalf of 30 former Caves of Barbados employees who the union leadership says have not been paid their promised pensions and gratuities since being made redundant two years ago.Deputy General Secretary of the island’s largest public sector trade union Wayne Walrond on Monday described the situation as scandalous and vexatious.Walrond said the workers, who were transferred from the National Conservation Commission (NCC) to the Caves of Barbados had still been employed under the NCC board and were promised their monies within six months of retrenchment.“We would have thought by now that all of the transactions and processes would have been cleared for the insurance company to pay the money, but to date, we are still hearing that these workers are suffering. We are very annoyed and they could come to NUPW and picket.
