RMT infrastructure workers to strike at GrantRail Publication Date: June 1 2006

AROUND 250 RMT members at rail infrastructure firm GrantRail are to strike for 24 hours from a minute after mid-day on Saturday after the company failed to honour a pledge to recognise the union, despite it representing a majority of the workforce.

"It is time for GrantRail to do the honourable thing and recognise the union that the majority of its workforce have chosen to represent them," RMT general secretary Bob Crow said today.

"Last summer the company said it would reognise RMT if we could show that the majority of the workforce had joined. We did that, but for some reason the company has failed to stand by that pledge.

"GrantRail already recognises those RMT members who transferred to GrantRail from Jarvis contracts, so it is hardly asking for the moon to expect them to enter a proper working relationship with the union.

"For a company that styles itself as a major player in the rail infrastructure industry, it is baffling why they appear to have buried their heads in the sand.

"Only 19 people voted against taking strike action and it should be clear to the company by now that its workforce is serious about being represented by a union with more than a century's experience in the rail infrastructure industry," Bob Crow said.
