I do not get paid to get to any job. My company does not charge any travel. However, I do not find it hard at all to cover my day from when I leave my house until I get home. I don't let the office do my quotes, I do them myself and always add a little time in there for my driving. Unethical? I wake up in the morning, get dirty during the day for one reason, repair customer forklifts. Someone is going to pay me. My customers never complain because I do a good job and don't have callbacks. Good techs are hard to find and customers really appreciate them.
As far as GPS goes. I hear rumors that my company is going to install GPS on the service vans. I will not do anything different. If anything is said to me, there are loads of jobs out there for good techs, I'm not real worried about it.
