Staff voted for the deal at a second ballot held last weekend. The positive outcome means that a 3% pay increase will be implemented now, to be followed by another 3% rise in January next year.
Burton's management and leaders of the Bakers, Food & Allied Workers Union had worked together to persuade staff at the site, where Jammie Dodgers and Cadbury Fingers are made, to change their minds.
"We are pleased that members of the BFAW at our Blackpool site have voted in favour of our revised pay package," said a Burton's spokesman. "We have worked collaboratively with union representatives throughout the process to reach an agreement and we feel the revised package is a fair and reasonable settlement."
The resolution brings to an end a long-running pay dispute that nearly resulted in strike action at the end of June when an earlier pay offer was rejected.
