Larry has worked for a 2,500-employee chemical manufacturer, ABCHEM, for 2 years. He went to work on Monday morning to find his key no longer fit the front door lock and a new sign—FUTURE HOME OFFICE OF ALLIED PLASTICS—on the front door. He called his office and found that the telephone had been disconnected. He then noticed the local paper with headlines, "ABCHEM Sells Plastics Subsidiary: 2,000 Layoffs!" Larry remembered the letter he received from the HRM department 3 months earlier that had warned of this probable plant closing, but he ignored it as a rumor. Which protection is Larry given under WARN?
