Wrongful Termination Employment Lawyers Diamond Bar

Wrongful Termination in Diamond Bar: How California Law Applies

Most jobs in California are at-will under Labor Code section 2922, which generally allows an employer to end employment for any reason, with or without notice. However, the at-will doctrine is not absolute. Wrongful termination arises when the reason for the firing violates a specific statute, an employment contract, or a fundamental public policy.

For employees who live or work in Diamond Bar, claims are pursued under California employment laws such as the FEHA and the Labor Code. Civil lawsuits originating in Diamond Bar are typically filed in the Los Angeles County Superior Court, East District, specifically at the Pomona Courthouse South.

Common Legal Theories in Wrongful Termination Cases

A termination can be unlawful even when an employer labels it performance-based or a layoff. A legal analysis focuses on the underlying motivation and the evidence supporting pretext.

• Discrimination under the Fair Employment and Housing Act (FEHA): Termination motivated by protected characteristics such as race, religious creed, disability, or age.
• Retaliation under FEHA: Termination occurring after an employee engages in protected activity, such as requesting medical leave or reporting harassment.
• Whistleblower Retaliation: Termination after disclosing information regarding a violation of state or federal statute to a government agency or a person with authority.
• Breach of Contract: Established in Guz v. Bechtel National, Inc. (2000), if an employee has an express written or implied oral contract requiring good cause for termination, the employer must adhere to those terms before executing a dismissal.
• Wrongful Termination in Violation of Public Policy: Established by the landmark case Tameny v. Atlantic Richfield Co. (1980), the law allows employees to sue for damages if their discharge violates a fundamental public policy. Green v. Ralee Engineering Co. (1998) expanded this by allowing public policy claims to be based on administrative regulations. Most recently, Hearn v. Pacific Gas & Electric Co. (2025) reinforced that employees terminated for reporting safety hazards affecting the general public have strong grounds for a Tameny claim, even if the hazards were internal to the company’s infrastructure.

Filing Claims and Seeking Remedies

Before filing a lawsuit for harassment, discrimination, or retaliation under FEHA, an employee must exhaust administrative remedies by filing a complaint with the California Civil Rights Department (CRD) and obtaining a Right-to-Sue notice.

In a successful wrongful termination lawsuit, remedies may include past and future economic damages, non-economic damages for emotional distress, punitive damages, and attorney’s fees. Employees have a duty to mitigate damages by actively seeking comparable new employment.
