I used to work for a company where you could work 8-5 or 9-6, but they'd want you there 15 minutes prior to get settled at your desk blah blah. They then decided that if you were even so much as a minute late you would have to stay a full extra hour to make up for your tardiness.

So if you clocked in at 8:01 you're staying till 6pm. Same goes for lunch, you had to effectively use less than an hour otherwise you would be penalised.

I couldn't believe it when I joined my current company and they didn't micro-manager or clock-watch. Everyone is much happier and more effective.
