When an employee raises a complaint about wages, working conditions, discrimination, harassment, safety, or another workplace issue, how the employer responds can become just as important as the underlying complaint. California law protects employees from retaliation for exercising certain workplace rights, including raising concerns about workplace conditions or participating in investigations. In 2026, California also implemented the Workplace Know Your Rights Act, which requires employers to provide employees with an annual notice explaining several workplace protections, including protection from retaliation.
Business owners should avoid treating employee complaints as informal conversations that do not require documentation. A complaint should generally be recorded with the date, nature of the concern, individuals involved, and steps taken by the company. Employers should also be cautious about making employment decisions involving an employee shortly after a complaint is made. A legitimate business decision may still be challenged if the employer cannot clearly explain and document the reason for the decision.
Documentation should focus on objective facts rather than conclusions or personal opinions. Employers should also apply workplace policies consistently to similarly situated employees.
A Practical Employer Checklist
When an employee raises a workplace concern, business owners should consider:
- Documenting the complaint and the date it was received.
- Identifying who will review or investigate the issue.
- Preserving relevant emails, messages, time records, personnel documents, and other evidence.
- Avoiding retaliatory or disciplinary action simply because an employee made a complaint.
- Applying company policies consistently.
- Separating the investigation from unrelated performance-management decisions when appropriate.
- Documenting the legitimate business reason for any subsequent employment action.
- Consulting employment counsel when the complaint involves potential discrimination, harassment, retaliation, wage-and-hour violations, or threatened litigation.
For California business owners, good documentation is not simply an HR task—it can become important evidence if an employment dispute reaches mediation, arbitration, an administrative agency, or court.
