I've audited lots of companies, and some do have penalties for long breaks, lateness etc. Some don't care how little time you spend in office, as long as you get your job done.

This is called company culture, is it not?

My current company has an electronic door pass system. So we have to flash our cards every time we exit the main office area ie. to go the lift lobby, pantry, toilets, fire escape etc. Every time we flash the card, the details are recorded. Our admin has exact records of how much time we spent each day in the office, what time we come in leave, how many toilet breaks, trips to pantry, smoke (fire escape!). So, if the company wants to be really uptight about the 40 hours per week, 8.30am - 5.30pm written in our employment contracts - they can. But then again, our culture is "You are free to come and go as long as you get the job done. Just don't overdo it".

I know someone in admin knows I come in at 9.30/10am each morning and leave by 4.30/5pm. But I also know someone in IS knows that I do email at night and during weekends. My boss knows that when I travel on business, I lose my nights and my weekends. So, it's all ok. The culture permits it.

At the end of the day - you should look for a company which culture you enjoy. Otherwise, you have to learn to tolerate it. If you can't tolerate, you should leave. You won't thrive there.
