Workers at the National Gallery threatened with outsourcing will be on strike for seven more days on 14 and 15 March and 24-29 March.
Gallery bosses plan to outsource 400 staff, including guards and visitor assistances.
CIS, the company that will employ the staff once outsourced, has contracts in many industries, meaning that staff could be transferred to other workplaces.
PCS union also argues that TUPE protections only protect existing staff, and new staff can be employed on worse terms and conditions.
In The Guardian on 20 January, Polly Toynbee revealed how CIS removed chairs used by gallery guards when bought in to run one current exhibition.
PCS says the gallery has also reneged on a previous agreement to pay the London living wage.
Workers are asking for support on picket lines, particularly on the weekend, which start at 7am every day. They are also hosting a conference on the “future of arts and culture” on Saturday 14 March.
