JPMorgan Chase will eliminate 2,800 more jobs at Washington Mutual through attrition, bringing to 12,000 the total number of positions lost since the bank purchased the failed thrift in September 2008.

The new job losses follow a decision in December to cut 9,200 jobs nationwide at WaMu.

JPMorgan paid $1.9 billion for most of WaMu, including branches and deposits, after the thrift was taken over by the FDIC.

New York’s JPMorgan expects to keep most of the WaMu branch employees, and will shutter less than 10% of the combined company’s retail outlets.
