Staff working in museums at some of Greenwich’s most iconic landmarks went on strike on New Year’s Day – and there may be more strike action in the future.

Workers at the National Maritime Museum, Queen’s House and Royal Observatory picketed outside the landmarks on the first day of 2018.

Trade Union Prospect said the dispute with Royal Museums Greenwich (RMG) is over new shift patterns which removed paid breaks and opportunities to work overtime, lowering worker’s pay as a result.

Part of the reason behind picketing on New Year’s Day was so less of the public would be impacted by the strike, but a spokesperson from Prospect said the issue had not yet been resolved and “there is always an option to take further strike action”.

Prospect negotiations officer Caroline Hemmington said: “It has been a very difficult decision to take strike action.

“However, negotiations with RMG and subsequent changes have left staff feeling undervalued with no other option.

“Prospect is calling on the RMG to give back decent breaks or compensate accordingly. Ultimately, staff want to see their employer join other leading organisations in paying London Living Wage.”

A spokesperson from RMG said: “We very much regret that they feel this is necessary as the new system seems to be bedding in well but at the same time we acknowledge and respect the professionalism shown by all staff as they strive to maintain our service to visitors.”
