Local 54 of the Unite-HERE union will hold its fourth demonstration outside the casino Friday evening. Another is planned for most of Saturday.
Contracts between the union and nine of Atlantic City's 11 casinos expired Thursday, and no new talks are planned for the next few days.
Casinos want pay cuts as part of a new deal. Resorts slashed worker pay dramatically when new owners took over last December, saying the lower pay was needed to save the struggling casino.
Housekeepers, servers and other service employees are working without a contract, but both sides are honoring terms of the expired deal.
