NEW YORK, March 20 (Reuters) - JPMorgan Chase & Co said Friday it will give "front line employees" a one-time bonus of $1,000, paid out in two installments in April and May, according to a memo sent to staff and seen by Reuters.

The largest U.S. bank by assets, which closed 1,000 of its roughly 5,000 branches this week, said full- and part-time staff who still have to go into an office or Chase branch to do their jobs are eligible to receive the payments.

These staff must also make an annual salary of less than US$60,000 or be an employee based at a consumer banking branch. (Reporting By Elizabeth Dilts Marshall; Editing by Kevin Liffey)
