Talks between a group of different unions and the company over working conditions did not yield any results, the statement said.
"Any flight cancellations or disruptions resulting from these days of action will be solely attributable to easyJet, which has chosen not to give a serious response to the repeated warnings from trade unions over the past months," the statement said.
Spokespeople for easyJet did not immediately respond to a request for comment.
The London-listed airline is in the process of being bought by investment fund Apollo (APO.N) in deal valuing the airline at £5.70 billion ($7.70 billion).
