AGENCY workers on Great Western Railway (GWR) have announced strike action against a “scandalous” shift change which they say will have them each working an extra 60 shifts a year.

Workers employed to clean new trains supplied by Hitachi by the subcontracting giant ISS will strike for two days from Thursday 11 July over the imposition of new shift patterns.

A ballot for strike action returned a 100 per cent Yes vote and they are demanding that the current work patterns be kept.
