When the new labor law limiting the working hours of waitresses to nine hours at a stretch goes into effect tomorrow, it will have no application to the waitress in the House and Freshman dining halls and in the Union, according to a ruling by the State Labor Relations Board.

Because Harvard is an educational institution and therefore renders a public service, the Board decided that the rule cannot apply to the four hundred odd waitresses employed by the University. This decision confirms the findings of the lawyers who were examining the case last week.

The ruling of the Labor Board obviates any grounds for the rumored strike on the part of the employees.
