Certain circumstances exist that permit deviations from the standard protocols governing substance screening within the state. These deviations, often rooted in specific industry regulations or collective bargaining agreements, carve out specific instances where the general statutes do not fully apply. For example, federally mandated safety-sensitive positions, such as commercial truck drivers, adhere to federal regulations that may supersede state laws regarding testing protocols and frequency.
Understanding these deviations is crucial for employers operating within California. Proper adherence to applicable regulations prevents potential legal challenges and ensures compliance with both state and federal mandates. Historically, the evolution of these regulations reflects an ongoing negotiation between employee rights to privacy and an employer’s responsibility to maintain a safe and productive work environment.
