I expect we'll be seeing a lot more of this type of disciplinary action being taken. A few weeks ago we had our Telematics meeting to let us know how it's going to be from now on. Our division manager said it straight out: you will take lunch on trace, even if that means you bring a bag lunch to work (like he did for 10 years, according to him). He showed us a lot of neat Powerpoint slides of a driver who drove all around town on the clock, at a pizza joint for 45 minutes, at a park for a couple of hours, etc. Obviously this guy was stealing time, but they are apparently using that example as justification for eliminating any deviation from trace that does not involve making service on a package. Doesn't matter whether you are off the clock while driving off route, they don't want to spend the fuel cost either.
Heads up to all of you out there, Telematics/Big Brother is no joke. I have been pushing the envelope a little every few days, just to see what Telematics can and can't catch. It catches everything, as far as I have been able to tell. My advice to everyone is to work as directed. Sucks that they didn't give the OP any warning that he was doing anything wrong before they fired him, they gave us that much courtesy here, at least.
