CLEANING and maintenance workers at Scotland’s biggest railway station will strike later this month over “scandalous” working conditions.

Their union RMT said contractor ISS had reneged on promises to improve staff accommodation facilities and instal air conditioning. 

Members are instructed not to book on for any shifts on Sunday January 27.

RMT general secretary Mick Cash said: “The fact that low-paid ISS contractors are being forced to strike over broken promises to improve workplace conditions is a scandal and the company should be hanging their heads in shame.

“The working facilities inflicted on this core group of rail support staff are a disgrace to the railway in Scotland and an appalling indictment of the way that private contractors think they can get away with treating their workforce.”
