The American Bar Association is offering its first-ever employee buyout in advance of a planned major reorganization this spring.

Employees with at least 20 years of service—and whose age and years of service combined equal at least 75—will receive 15 months of their base pay if they choose to leave, ABA executive director Jack Rives said in an interview Thursday. The buyout comes at a time when the ABA is grappling with revenue declines and a shrinking number of paid members.
