It's not that most places have HID cards. Most big places do. Most small businesses don't. I kind of ended my post before I finished saying my thought too. My pack of HID cards were for various buildings, suites, and datacenters. Individually each knew when I came and went, but to them I was a customer. My company didn't know when I went through any of those doors. As far as I know, no one but me ever called to check up on anything. Even then, it was rare.
I used last a lot to make my own timeline on events, but that was just to notate a report on a job.
It's better to log in and out properly, so you can see what you did, but your coworkers are getting around that by staying on. Eventually it may catch up with them, if someone finally asks, "Why are you shown as working 24/7/365?"
When I was in charge of the department, I didn't really care how many hours people worked. I cared that the tasks were accomplished in a timely fashion. I told them on day 1, they have to work what the job dictates. If it's 20 hours or 80 hours in a week, you have to do it. I was very fair with them though, and the weeks were usually 20 to 30 hours. Occasionally things got busy, and they were happy to work the longer hours as required. They knew if I said "I need you for this.", it was because I really did, not because of an artificially created deadline to squeeze extra work from them. If it was something that could wait, I'd cut them off at about 8 hours, and say "just finish it tomorrow." But, if it was mission critical, we stayed on it. By "we" is was usually all of us. Since I was in charge, I took a lot of the really important tasks myself, so they weren't overworked, and then they'd volunteer to help. It made for a really good teamwork environment. That's something that is overlooked by most places these days.
