Four people arrive to work the night shift in a meat factory. They meet for the first time. They are employed as cleaners by a temp agency. They are all on zero-hours contracts. Every shift, they clean. Every four hours, they take a break. They drink tea or coffee together. They read magazines. They chat. As it gets light, they go home or to another job. The cycle goes on. And on. Strangers. Until something stirs, until isolated people get too close to one another, too fast. Alexander Zeldin's brutally honest and darkly humorous play, written through devising with the ensemble of the premiere production, exposes stories of an invisible class. It received its world premiere at The Yard on 1 July 2014 and transferred to the National Theatre's Temporary Theatre on 28 April 2015.
