Envoy management continue to screw with us every chance they get. The latest is their unilateral re-interpretation of how PVDs are handled. Past practice was if you had a lost day in a city, a single PVD would net 2 days off as the lost day contained no flying, and you would continue the trip from base. Taking the PVD next to a lost day would turn a 4 day trip into a 2 day trip. Now they will deadhead you to a station to sit in a hotel on the lost day after your vacation day, making the 4 day a 3 day trip with plenty of hotel appreciation time. Yet another unilateral change to work rules that negatively impacts our QOL.
