LAKE BUENA VISTA, Fla.?Dozens of workers picketed two hotels at Walt Disney World on Tuesday in a rare labor dispute for the area’s tourism industry.

The union representing housekeepers, laundry workers and public area attendants at Walt Disney World’s Swan and Dolphin hotels declared a strike.

But Treva Marshall, a spokeswoman for the hotels, said all employees scheduled to work had showed up for their shifts, and service was not disrupted.

Last week, the workers rejected for a second time a three-year contract covering 400 of the hotels’ 2,000 workers. Management said it would put the contract into effect unilaterally.

Workers wanted a guaranteed 40-hour work week and job assignments based on seniority.

Strikes in Orlando’s tourism industry are rare. Labor leaders could recall only two in the past decade: a musicians’ strike at Walt Disney World and one by hotel workers at the Grosvenor Resort. \
