First check w/ your State Dept. of Labor to find what their policies/guidelines are for attendence as this will help you develop a Corrective Action plan that will help hedge your unemployment costs. We found that in CT, an employee is given two(2)hours time from the beginning of their shift to call in absent for that day before thwey are considered a no call/ no show. Therefore separate exception codes had to be tracked to ensure a true record of attendence. This was an extemely sensitive issue for us as a call center as we operated as a P/L.
