“It weakens the position of all the guards for their to be fewer unionized workers. And it weakens campus unions at Harvard as a whole,” said Mackinnon, who participated in last summer’s protest to protect security guard jobs from outsourcing.

The parity policy was instituted after the Dec. 2001 Katz Commission report, which was prompted by a PSLM-led sit-in at Mass. Hall.

“It’s inconsistent with what Harvard said they were going to do,” said Mackinnon, who is also a Crimson editor.

Last June, LaBua said that the mix of in-house and contract security guards did not represent the best way to provide security for the school community.

“Any major employer would look at this and say there seems to be some merit in unifying all those forces,” said LaBua in June. “We are in the process of looking to unify the existing security guard force.”

CORRECTION:  This story incorrectly sourced information that the seven remaining Harvard-employed security guards whose positions will be eliminated will be offered jobs with Allied Security to James Herms.  Herms said that Allied Security would replace the guards, not that they would rehire them.
