On Thursday, workers held a rally outside a hotel near the Los Angeles International Airport.
Swift's tour is making a 6-night stop at SoFi Stadium next week and it's expected to pack local hotels. Members of UNITE HERE Local 11 have been on strike since their contract expired last month.
They're asking for better working conditions and higher wages to keep up with the cost of living.
A group representing the hotels said it has offered significant pay increases and said the union won't lower its demands.
