This discussion reminds me of my 2 favorite "business" songs. The first is "You get what you give" by the New Radicals and the 2nd is "Money changes everything" by Cyndi Lauper.
I am from management and do agree that there are some not so nice companies and some no so honest employees. My own experience has shown me road techs that call in and they are 60 miles away from where they say they are, one that made 300 copies on OUR, not his, customers copy machine, tell us that the van is broken down so they don't have to work that day, use their van for personal errands, use their van to deliver beer kegs to a party (really good advertising) etc.etc.etc. I'm sure that there are some that wonder what WE are doing wrong, but I would guess that many others have the same stories and worse.
Some of the things that you may not like, such as GPS, were probably instituted due to less than honest employees. My suggestion would be to get on their back and make them change if you don't like what they force management to do.
Business-wise I have no problem with a union, but personally I do. I don't want to make the same amount of money as a contributor to my company as a taker does and I certainly wouldn't appreciate the meager $.37 cost of living raise that everyone else gets. I would rather work for a small honest and get my $1.50 per hour raise when the taker gets nothing or maybe $.25. By the way if you have never gotten a $1.50 per hour raise-or more-try working for a smaller company.
About 20 posts ago I asked why it was OK for a tech to collect full pay for rework/call back/mistake when the company isn't collecting a penny and there was not a hint of a response. That's what is known as give and take.
