I think it may evolve to to that. Market share is dropping, competition is fierce and bottom line is may dictate employers to go that way. I can see us losing most of our perks soon as our door rates are lower now than years back. Many tech's destroy their company laptops or Ipads from carelessness. It will be replaced at no-charge to them. Most techs are abusing cell phone data by watching You-Tube or streaming videos. We have a company APP within our phones that shows our employer every key stroke we make, but tech's still abuse it. The company does track our every move with their supplied phones, and has software in laptops and I-Pads that "tells" them if we share info.
It's that proprietary info that would be an issue with personal laptops. the company would have no control of that info and could lose sensitive data on customers. There would be no controls in place, no security. Our company I-pads are linked directly to their server. If you try to access internet, it goes on wi-fi only and wont let you do any company business.
There is no single scan tool to use on lifts, like OBD2 on all cars, so it can get pricy for a tech with no access to most trucks
