The Carnegie Museum in Oakland is also listed.

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.
