Luisa has worked for a 2500-employee chemical manufacturer, PoySon, for two years. She went to work Monday morning to find her key no longer fit the front door lock and a new sign "FUTURE HOME OFFICE OF GREEN CO." on the front door. She called the office and found that the telephone had been disconnected. Her husband called her and mentioned the local paper with headlines, "PoySon sells plastics plant to a recycler: 2000 layoffs!!" Luisa remembered the letter she received from the HRM department three months earlier warning of this probable plant closing. To what further protection is Luisa entitled under W.A.R.N.?
