Protesters gathered outside Sotheby’s auction house in central London on Thursday of last week demanding the reinstatement of four workers.
Workers from the School of Oriental and African Studies and the National Gallery brought banners and joined the protest in solidarity.
The four—Percy, Barbara, Marco and Jorge—worked for subcontracting firm Servest.
The four joined a protest earlier this month calling for better sick pay and an end to victimisation of union activists.
The next day Servest told them Sotheby’s had said it did not want them on the premises.
But Percy said, “The support that we get from people gives us the strength to keep fighting.”
