It's the companies laptop. In your home.
If it's personal use, why aren't you using your own computer?
It's the company's truck. After hours.
Why are you driving the company truck for personal affairs outside of company time? This one, there is a *small* degree of leeway in favour of your argument, but generally our employees who have a company vehicle leave it at the company lot at the end of the day and have their own transportation to get to/from home. A small number of them dispatch from home, and park the company vehicle in their driveways overnight, but it's still really bad juju for them to take it on a grocery run after hours....
It's the company's phone. On a private call.
Why are you using a company phone to make a personal call? Especially in this day and age, when almost everybody has a cell phone....
Companies have the privilege (not right!) of monitoring their employees
Companies have a right to make sure they receive the contracted services for the money they're paying you. They also have a right to ensure you aren't misusing/abusing company resources. If you're on company time/using company resources, then it should be for the work they're paying you to do. If your company has a policy that allows you to use company resources for personal use when you're on your own time (just as my company does -- I'm posting this while on break, from my office PC), then you have to expect that they're monitoring it. If, for no other reason, then to make sure you aren't wasting their time/money when you're supposed to be on the clock.
We need to draw a line that says only conduct that happens on company time or using company resources is subject to any disciplinary action. We need to prohibit employers from taking action against employers punitively on the basis of race, sex, religion, national origin, sexual orientation, gender identification, etc. And this is not just about protecting "the little guy"; This is about protecting the country as a whole.
I agree with you completely here. Of course, I live in a country where we already have those protections. Every single one of the categories you listed has been read into the constitution and human rights/anti-discrimination legislations as protected classes of people.
Pervasive electronic monitoring is a strike against that goal.
It doesn't have to be. The company I work for has GPS trackers in the company vehicles. They monitor the location/speed of every company vehicle in the field, along with engine idle time, and people do get censured for driving like idiots or wasting fuel. They also monitor the data use on the cellular devices provided to employees, and make sure you're not wasting bandwidth, and disable data on company-provided equipment where people are using too much. On company PC's, everything is logged and goes through a proxy. Every phone call made, both on cellular and desk phones, is recorded, and if you're logged in to your PC at the time, screenshots of what's on your screen during the call are recorded as well. It's company resources, and this kind of monitoring is completely reasonable -- They don't care what I do on my own time or with my own equipment, but they do (reasonably) have a right to expect that I'm not going to waste their money, and that I am not impaired while on company time.
