The Exelon plant across from the Encore Boston Harbor and Hotel is the largest power plant in Massachusetts.
Union employees of the sprawling energy complex went on strike Saturday claiming safety issues and concerns about working conditions.
Throughout the weekend, the Utility workers Union of America Local 369 manned a picket line in front of the entrance to the facility.
Exelon officials declined to answer inquiries about the strike.
The picket line attracted media coverage over the weekend when Congressman Joe Kennedy, running against Senator Ed Markey for the Democratic senate nomination, lent his support to the strikers.
It was the second time in two weeks Kennedy has appeared in Everett.
Councilor Mike McLaughlin, running against State representative Joe McGonagle, also joined the picketing with Kennedy and Councilor Stephanie Martin.
The energy generating facility is located on a small spit of land along the shore of the Mystic River on the Everett side of the river which is considered Charlestown.
