Building workers' leader Alan Ritchie hit out, during his speech to the TUC Congress, at the massive exploitation of people and the vast profits made by agencies placing migrant workers on construction sites.
'My union came across a group of Eastern European workers employed by an agency in Glasgow. The company recruiting them was a multinational with millions of pounds in annual turnover.The agency employed them on less than £5 an hour.
'We also found an agency employing Polish plasterers on the minimum wage and deducting accommodation costs, airfares and Home Office registration fees from their wages.
'It's time the government woke up to this exploitation. Employers will pay lip service to the formal rights of workers. When the enforcement authorities are gone people like gang masters use fear and intimidation to force down wage rates.'
