For the first time in its history, Harvard yesterday submitted its labor difficulties to government regulation as University officials conferred with A.F. of L. and inside union delegates at a formal hearing before the State Labor Relations Commission.

The purpose of the three-cornered conference was to determine how best to group the employees when they vote next week on whether they prefer the A.F. of L., the inside union, or no representation at all. After mutual concessions it was agreed that there should be nine classifications.

A surprising feature of the agreement was the lumping into one of all kitchen and dining-hall employees. Other groups were the maids, the male caretakers, the maintenance department, the operating engineers, the non-operating engineers, the H.A.A. employees, the press and bindery employees, and the patrolmen. In the last four of these groups, totalling 130 men, there was no A.F. of L. opposition to the Employees' Representative Association.
