Concerned about subjecting your attendees to crowds of angry protesters outside hotels? Hoteliers may be unlikely to inform you of labor problems, but now you can access information from union activists via the Internet. The California Travel Advisory Web, launched by Hotel Employees & Restaurant Employees Union (HERE), Local 2850, in Oakland, CA, flags trouble spots, and includes a brief history of each labor dispute, alternatives to the boycotted hotels, and links to a HERE Web site listing union hotels nationwide.
