One thing that I don't has been mentioned here is: treat others how you would want to be treated.
If you treat your employees like h*ll - don't be surprised if it comes back and bites you in the butt. I've worked for at least a few egregious employers - One was so wound up about his employees showing up on time (no, not thirty seconds late, literally) he had a some satellite synchronized clock installed about the door. Guess what, he paid for it, when 5:00.00pm rolled around there was a cloud of dust in the parking lot (the front wheels of everyone's car were rolling, and the back ones spinning), and darned any work left on the bench, or it's importance. If you come across as a jerk to your employees - they WILL NOT look after you. Employees in their daily travels see all kinds of things, things we really have no real responsibility too (perusing logs, angry customers that we aren't dealing with, mistakes made by the last guy who was here,etc.) - I cannot stress this enough be good to your employees - don't be accusatory by default and take some third grade teacher tone with them on the phone with them.
I saw at the beginning of this people were stating things like: 'back in the day, you couldn't do your banking online, so just because technology has changed the fact that you can bank online now, doesn't mean you should "steal" from your employer by paying a bill' - B.S. I SAY - employee / employer relationship has changed too - you've conveniently overlooked that....we don't work on time cards anymore putting in our '40' - it was unheard of 30 years ago to stay and work because a clients PDC was down and know you were not going to get paid for it.
