The Equality and Human Rights Commission (EHRC), a public body in Great Britain established by statute in 2006, has written to all five Magic Circle firms to warn that it could take legal action if they fail to take appropriate action to prevent and respond to sexual harassment in the workplace.

The EHRC has sent out letters Monday to Allen & Overy (A&O), Clifford Chance, Freshfields Bruckhaus Deringer, Linklaters and Slaughter and May—along with a range of other leading employers, including FTSE 100 companies—to request evidence of how they are tackling the problem of sexual harassment.
