Cigna Corp. will take an after-tax charge of between $30 million and $40 million in the recently completed fourth quarter related to the moves.
Cigna joins competitors Aetna Inc. and UnitedHealth Group Inc. in trimming staff. Aetna said last month it would cut 1,000 jobs, or nearly 3 percent of its work force.
UnitedHealth announced plans to cut 4,000 jobs last July.
