To maintain pass travel for the following month you must work a minimum of 6 work days in a month. The ONLY days that do not count as days worked are days lost via trip drops and sick days when you do not have enough sick time to cover the absence. You have a 2 days trip worth 8 hour, 4 hours per day. Prior to departure you call in sick for the entire trip. You have 2 hours in your sick bank. You would get credit for one day worked in this example.
