Hogan Lovells has offered voluntary retirement to hundreds of its support staffers in the U.S. in a bid to trim its ranks of senior business services workers. The proposed cutbacks come on top of the 90 roles affected by a U.K. restructuring plan unveiled Monday by the firm.

About 400 of Hogan Lovells’ business services staff in the U.S. who have been with the firm for at least five years will be invited to take voluntary retirement. The global legal giant said that it expects between 5 percent and 10 percent of its U.S. staffers will take up its offer, equating to roughly 20 to 40 employees.
