Some 2,000 food and beverage workers were threatening to strike amid stalled negotiations. UNITE HERE Local 11, which represents the workers, announced the deal at a news conference Tuesday.
Union members still need to vote to approve the deal.
Workers were seeking higher pay, better safety rules and a ban on ICE agents at the stadium.
Kurt Peterson, co-president of the union, outlined some of what the workers are getting as part of the dea.
"This is a historic agreement. Economically, it is the strongest agreement at any NFL stadium. We won massive raises. Most workers will earn more than $40 an hour and many will earn substantially more," said Peterson. "Tip workers will see their pay increase by at least 30%. We won premium pay for the World Cup and the Super Bowl. We won major protections against subcontracting and automation."
Peterson said they also won a "significant ongoing contribution" to build housing for hospitality workers.
"We even won an expiration date of - get this - April 30, 2028."
The World Cup is expected to draw millions of fans to matches across the U.S., Canada and Mexico, over 39 days this summer.
Eight matches are scheduled for SoFi Stadium, starting with Friday's match between the U.S. and Paraguay. During the World Cup, the venue will be called Los Angeles Stadium.
