I am an Overnight Loss Prevention Agent for a Wal-Mart store in N.Y. I have been suffering from shortness of breath and excessive coughing. I have called out the past three days and need advice. The store i work at is currently going through major renovations to make it a Super Center. The Office I is in the middle of the construction zone. During the last three months all walls from Offices, Staff Lounge and Back Warehouse have been demolished. I can no longer work in such an unfit environment. All other offices such as managers offices, Personnel, Employee Lounge and Warehouse operations have been moved. I have not filed an incident report nor an LOA yet for fear of a whistle blowing backlash.
