PITTSBURGH (KDKA) – Carnegie Museums is reworking its security staff.

According to a a spokeswoman with the Carnegie Museums, the 76 affected positions are all security guards. They are being asked to re-apply for their jobs with a contractor the museums will use for their security services.

The Pennsylvania Department of Labor’s website lists the Carnegie Museum of Art, Natural History, the Science Center and the Andy Warhol Museum as some of the locations the staff will be re-worked.

The Carnegie Museum in Oakland is also listed.

Betsy Momich, director of corporate communications for the Carnegie Museums, says no workers at the library will be affected.

Rather, it’s the 20 full-time and roughly 55 part-time security guards who work at the four museums.

The museums are contracting with a security firm, 3G Security Solutions, for their security guard needs.

Momich says the museums are having more evening events, more special events and a variety of exhibitions that require security guards on the premises.

In the best interest of the museums, they believe contracting out security services in the future is the best option.

The contractor will cover staffing and training of the security guards.

Momich says current security guards are being encouraged to re-apply for their positions.

The changes will be effective as of July 8.
