Layoff timeline
1 EVENTStrauss Borrelli PLLC is investigating Riggs Ambulance Service, a division of Sierra Medical Services Alliance (SEMSA), over a potential violation of the federal WARN Act after the company notified the California Employment Development Department on October 31, 2025 of a mass layoff at its Merced facility. The firm alleges Riggs Ambulance Service laid off 181 employees and may have failed to provide the required 60 days' advance notice, which could entitle affected workers to back pay and benefits. The investigation is probing whether the employer met WARN Act obligations for covered employers with 100 or more employees. The notice and the firm's outreach invite impacted employees to contact Strauss Borrelli to discuss potential legal remedies related to the alleged improper timing of the layoffs.
