A leading teachers’ union is charging that Government’s widely-publicised summer rehabilitation programme at the island’s schools appears to be hindered by a lack of funding and shoddy workmanship that has left some campuses plagued by mold, leaky roofs, overgrown fields and termite-infested walls.So dire is the situation at some of the learning institutions, that the Barbados Union of Teachers (BUT) is demanding that the health and safety conditions of several school plants be given the full and urgent attention of the Ministry of Education.Julian Pierre, the chairman of the union’s Occupational Safety and Health Committee told Barbados TODAY in a recent interview that only a small portion of the island’s schools fell under the annual summer maintenance programme but many others were in desperate need of attention.He said the programme over the years has failed to produce quality results as it has been impacted by poor work.
