None, I can't think of a single negative thing about working at plumbline. Any comments on this page about plumbline being a bad place to work were probably dishonest in some way, if there is one thing they actually push for it is never ripping off the customer or selling something they don't really need. If you're an honest plumber that loves what you do plumbline is a perfect fit and you won't have any issues with this but if you're dishonest or sell people things they don't need then it's probably not a good fit for you, the CEO is an extremely moral and honest person and has no tolerance for that
