Professional kitchens have always seemed like pressure cookers: hot, sweaty, stressful. The caricature of a head chef is angry, sweary, unable to keep a lid on his temper. He shouts at underlings for the most minor of infractions.

Recent events have shown how pervasive that stereotype still is. A number of ex-employees of the Kitchin Group, the set of restaurants owned by celebrity chef Tom Kitchin, have made allegations of a range of abuse, from being denied food, drink and breaks to deliberate burning and sexual harassment.
