When testing is permitted
​
-
Pre-employment: An employer can require a drug and alcohol test after a conditional job offer but before the employee begins work, provided the policy applies consistently to all applicants for that position.
​
-
Reasonable suspicion: If an employer has specific, observable evidence (based on appearance, behavior, speech, or body odors) that an employee is under the influence of alcohol, they can require testing.
​
-
Post-accident: Testing is allowed following a serious workplace accident, particularly if there's reasonable suspicion alcohol was a contributing factor.
​
-
Safety-sensitive positions: Random alcohol testing may be permissible in very limited circumstances for employees in positions deemed safety-sensitive, where impairment could pose a direct threat to safety, such as operating heavy machinery or in transportation industries regulated by the Department of Transportation (DOT).
​
-
Federal requirements: Certain federal laws, like the Drug-Free Workplace Act of 1988, mandate testing for employers holding federal contracts or grants above a certain value.
​
What's generally not allowed
​
-
Random alcohol testing: Random alcohol testing without reasonable suspicion is generally prohibited in California for most positions.

-
Discrimination: Testing must be conducted fairly and cannot be based on an employee's protected characteristics (race, gender, etc.).
Employee rights
​
-
Privacy: California law recognizes an employee's right to privacy, which must be balanced against the employer's need for a safe workplace.
​
-
Notice: Employers should provide employees with notice of their alcohol testing policy, outlining when and why testing might occur.
​
-
Confidentiality: Test results must be kept confidential and shared only with individuals who have a legitimate need to know.
-
​
-
Second opinion: Employees have the right to request a second opinion from an independent testing facility if they dispute the results of an alcohol test.
