Advanced Pressure Technology

Strauss Borrelli PLLC is investigating Advanced Pressure Technology (AP Tech) for a potential WARN Act violation after AP Tech notified the California Employment Development Department on October 2, 2025 of a decision to conduct a mass layoff at its Napa, California facility. The firm alleges AP Tech may have failed to provide the required 60 days' notice before laying off 237 employees and is exploring whether affected workers are entitled to 60 days of pay and benefits under the federal WARN Act. AP Tech, a subsidiary of SMC Corporation, designs and manufactures high-/ultra-high-purity gas delivery components. The notice triggered the investigation into whether AP Tech violated WARN requirements by not giving timely written notice to employees and government parties, and the law firm is soliciting contacted employees for potential legal remedies.
