My policy - you can do whatever you want, incl. working 30 minutes per day, as long as your boss is happy with your performance. If at any time the boss points out that you're not as efficient as he'd like, you can choose to either work harder or find another job.

This approach makes the job contract fair - the boss pays you the minimum amount (or close to it) that you find acceptable, and in exchange you work the minimum amount (or close to it) that he considers acceptable. No reasonable businessman expects you to be killing yourself while working for him - they certainly can _hope_ that you will, but they know that it requires a sucker.

A lot of people think like OPs coworker, it’s a surprisingly polarizing topic. Personally I think anyone who thinks writing a lot of code (irrespective of time) is a good thing is misguided at best.
