As a general rule, searches can be made of employee lockers and desks located on the premises of the company:

The most appropriate basis for conducting searches of employee lockers and desks is through employee consent. When employees are informed that their personal belongings, which may include lockers and desks, are subject to search by company policy, and they provide consent, the company exercises its right to ensure safety and compliance within the workplace.

Consent demonstrates an agreement between the employer and employee regarding the search. This is particularly relevant in protecting the rights of employees while also enabling the employer to fulfill responsibilities related to security and safety on their premises. Such practices often align with established organizational policies that notify employees of potential searches as part of their engagement and during orientation.

The other options do not provide a valid rationale for conducting these searches. For instance, searches without consent can lead to legal complications relating to invasion of privacy. Additionally, while local police may be involved for criminal investigations, their authority does not apply to routine workplace searches unless specific legal grounds are established. Lastly, discretion by a security manager is also not adequate justification unless it falls under the guidelines outlined in the company policy and after obtaining consent.
