Recent mandates by several practice group leaders at Morgan, Lewis & Bockius that attorneys show up three days a week offer the latest sign that Big Law is exercising a firmer hand on office attendance.

According to an email leaked by Above the Law, Morgan Lewis litigation chair J. Gordon Cooney is the latest practice group head in the firm to increase the group’s in-person days. Other departments named in the email include the firm’s corporate and business transactions group, its labor, employment and benefits group and its investment management group as other practices that have recently increased their in-office presence.
