PBS only works well if the trip pairings put into the system are good.
In the case of my company, we just started using it and most are unhappy. The main problem for us is the very low staffing levels!! We could hire a couple dozen people and maybe it will make a difference.
My experience has been the same as most. My lines have been ok at best. Very few days off and somewhat commutable.
IF you are in the top 10% of seniority you will love it. Other than that ...good luck!
