In California, Labor Code section 3550 requires every California employer to post the official workers' compensation notice in a conspicuous workplace location. The section 3550 California poster informs California employees of their right to file a comp claim and the §3700 employer insurance requirement; failure to post is a misdemeanor.
California Labor Code section 3550 requires every California employer subject to California Labor Code §3700 California workers' compensation insurance obligations to post, in a conspicuous workplace location, the official workers' compensation notice prescribed by the California Division of Workers' Compensation. The section 3550 California notice informs California employees of their statutory right to file a workers' compensation claim, identifies the employer's workers' compensation insurance carrier, explains how to access medical treatment for an industrial injury, and lists the contact information for the California State Information and Assistance Officer. Failure to comply with the section 3550 California posting requirement is a misdemeanor under California law.
Under California Labor Code section 3550, the California workers' compensation poster must contain specific information prescribed by the Division of Workers' Compensation: the employer's workers' compensation insurance carrier name and contact; the employee's right to file a workers' compensation claim under California Labor Code §3600 California for industrial injuries; the employee's right to medical treatment under California Labor Code §4600 California; the employer's medical-provider-network (MPN) information when applicable under California Labor Code §4616 California; the I&A officer contact information for free help with the claim; and the prohibition on retaliation under California Labor Code §132a California. The section 3550 California poster is updated periodically by the Division to reflect statutory changes.
Under California Labor Code section 3550, the California workplace poster must be displayed in a conspicuous workplace location where California employees can read it during work hours — typically in break rooms, employee lounges, near time clocks, or in central workplace areas. The section 3550 California rule requires the poster to be visible without unusual effort and to remain posted at all times. For California multi-site employers, each separate workplace location must have its own section 3550 California posting. For California remote-work and gig-work arrangements, the section 3550 California rule is supplemented by California Labor Code section 3551 notice-of-claim-information rules for individualized employee notice.
Under California Labor Code section 3550, failure to post the required California workers' compensation notice is a misdemeanor punishable by fine and potentially county-jail time, similar to the California Labor Code §3700.5 California criminal exposure for failing to carry workers' compensation insurance. The section 3550 California civil enforcement runs through the California Division of Labor Standards Enforcement, which can issue citations and fines against non-compliant California employers. The section 3550 California posting failure also creates evidentiary problems for the California employer in subsequent claims — a California worker who can show the employer failed to post may overcome certain statute-of-limitations defenses under the California Labor Code §5400 California 30-day notice and California Labor Code §5405 California one-year filing rules.
Under California Labor Code section 3550 (workplace poster), California Labor Code section 3551 (individual notice of claim information), and California Labor Code §3700 (insurance requirement), the California employer's notice-and-coverage obligations stack. The California Labor Code §3700 California rule requires the employer to carry workers' compensation insurance; section 3550 California requires the workplace poster; and section 3551 California requires individualized written notice to each California employee at hire and at the time of an industrial injury. The three California sections together ensure every California worker is informed of comp rights at multiple points; the California employer who skips any of the three faces civil and criminal exposure under the comp statute.
