Thousands of hotel workers marched on Tuesday from the Inter-Continental Hotel to the J.W. Marriott in downtown L.A.
The union wants an immediate $5 an hour raise, plus another $3 in subsequent years of the contract.
The hotel bargaining group says its last offer included an increase of $2.50 an hour in the first year, and a $6.25 increase over four years.
All hotel operations have continued during the strike.
