 Cleaners and porters at Sotheby's New Bond Street auction house were employed by Contract Cleaning and Maintenance (London) Limited (CCML), who conceded several demands after UVW initiated a formal dispute and 24 MPs signed an Early Day Motion condemning a litany of "poor employment practices".Sotheby's then terminated their contract with CCML and brought in Servest, taking UVW's dispute back to square one.A surprise protest on the 1st of July 2015 sought to disrupt a major auction night including contemporary art by Andy Warhol and Francis Bacon.
