More than 200 Public and Commercial Services union (PCS) members employed by National Museums Liverpool (NML) have already taken 56 days of action in protest at the non-payment of a cost-of-living bonus.
The action affects the Museum of Liverpool, the World Museum, the International Slavery Museum, the Maritime Museum, the Walker Gallery, Sudley House and the Lady Lever Art Gallery.
The new action will see members walk out at 11 weekends and half-term week from May until July.
PCS general secretary Fran Heathcote said: “Our hard-working members at National Museums Liverpool love their jobs but are angry and feel undervalued because NML is the only one of more than 200 employers covered by the civil service pay remit guidance to withhold the £1,500 cost-of-living bonus.
“This dispute can be easily resolved if the employer agrees to pay our members what they are owed. If the employer fails to do that, our members will go back on strike over the next three months.”
PCS acting national president Martin Cavanagh will speak at a rally outside the Museum of Liverpool on Liverpool’s waterfront today (Saturday, April 13).
