Just in time for Father's Day, Orrick, Herrington & Sutcliffe is expanding the relatively generous parental leave policy the firm introduced two years ago.

Orrick is tweaking its “onramping” period—the first month after lawyers return from primary caregiver parental leave, when they can take on half of their usual workload and still receive full pay—to allow its rank-and-file to set a predictable schedule in which they work no more than six hours in any given day. The firm is also increasing non-primary caregiver leave for attorneys and staff, and it will contribute $250 to a 529 college fund for its employees' new babies from now on.

Those changes build on the policy Orrick adopted in 2015, which allows primary caregivers to take 22 weeks of paid parental leave and an additional nine months of unpaid leave, and which firm leaders say is the most liberal at any major U.S. firm.
