FURIOUS workers at a Glasgow Remploy plant could take more unofficial action in the wake of a sit-in by dozens of staff at the factory.
Today's warning came as a protest was held at the Springburn factory yesterday after bosses refused to reveal the identity of a firm interested in acquiring the site which manufactures wheelchairs.
GMB union convener Phil Brannan today said: "I can't rule out more unofficial action. Members are extremely angry. We have tried to be reasonable and considerate but the company has not reciprocated."
Yesterday management said the site could attract a buyer but the firm's name remains a mystery.
This triggered a union meeting at which workers decided to stage a 90-minute sit-in.
Mr Brannan said that members wanted to know who the mystery buyer was so that the GMB could investigate the company.
But management say the negotiations are a confidential process and that "all the participants are covered by a non-disclosure agreement."
Today the 48-strong workforce began an overtime ban which is being enforced by colleagues throughout the Remploy network of 54 sites across the UK.
The Westminster government caused controversy by agreeing to axe 36 factories by claiming they all make losses. The hit list includes a site at Netherton Industrial Estate in Wishaw.
However, nine of the factories have been given a stay of execution, Springburn included.
Talks with potential purchasers come at a time when union leaders have called for a series of national 24-hour strikes with the first to be staged next Thursday.
