As part of the University’s effort to reduce expenses, Yale Security is reorganizing, which will mean eliminating two or three positions, including the director of security.

Yale officials said trimming top layers of management will simplify and streamline operations. The highest position, director of Yale Security, will be eliminated and replaced by more lower-ranking supervisors, said Deputy Secretary Martha Highsmith, who oversees campus security.

Officials said it is still unclear how many layoffs there will be. University Secretary Linda Lorimer estimated that two or three jobs could be lost.

Still, in September, Highsmith said Yale Security and the Yale Police Department finalized a budget for the 2010 fiscal year without any cuts to personnel. She said no security or police officers were let go “for obvious reasons.” Although casual part-time security officers have been replaced by full-time officers, she added, overall staffing levels have not decreased. Yale Security and YPD have cut some administrative costs, but Highsmith said those cuts will not affect student safety.

Lorimer added that Yale’s budget deficit prompted an examination of Yale Security to see how it could be made more efficient. She said she thinks the new force will also be more effective.

Yale Police Chief James A. Perrotti has often said that he considers Yale Security to be the eyes and ears of his department.

Since the endowment fell 24.6 percent in the 2009 fiscal year, Yale has delayed faculty hires, laid off about 100 staff and suspended most construction projects. These budget cuts have recovered $250 million of the initial projected budget gap of $350 million, Yale officials said.

But now the remaining $100 million will be more difficult to find, Levin said earlier this month. Salovey said at the time that the remaining cuts must be achieved by finding “little pieces.”
