MORE than 400 members of the Paper, Print, Wood and Allied Workers Union have been locked out at National Magazine Printers in Cape Town after the union staged a go-slow. The go-slow was in response to what the union calls futile wage negotiations and began on Wednesday afternoon, SABC Radio reported on Thursday. A spokesperson for management said they informed the workers that the go-slow would be considered industrial action and they would be locked out at 8pm on Wednesday. A spokesperson for National Magazine Printers said it was business as usual at the printing house.
