State investigators swarming on University grounds may be the result of a decision of the Massachusetts Labor Relations Board today after it considers the petition field by the A. F. of L. to investigate the legality of an alleged company union here.

Robert H. Everitt, organizer for Building Service local 30, said yesterday that once and for all he would attempt to break the power of the Harvard Employees Representative Association by eliminating the "unfair labor practice" of the rival union.

It was learned yesterday that representatives of the "inside" labor organization had demanded that Aldrich Durant '02 Business Manager of the University recognize their unit as the sole bargaining agents for maids and janitors.

Durant promptly communicated with Everitt, urging him to present his side of the case at the same time asserting that the "inside" union "seems to be entitled to an early decision."

The A. F. of L. Leader immediately began efforts to enlist State aid and to build up his union from 250 members to a full-fledged majority, entitled to bargaining rights.

Meanwhile the Employees Association maintained tight-lipped silence, refusing to reveal what they had asked of Durant and who their sponsor was.

Jeremiah J. Sullivan, who graduated from the Law School in 1930 and who was attorney for the "inside' union in its negotiations with the university Tuesday, decided on Everitt's plea to have nothing more to do with the organization.

Everitt indicated that the process of state investigation might continue for months and that the University would have no right to conclude an agreement with either one of the unions until a report had been made to Massachusetts authorities.
