Sorry, I wasn't able to express myself clearly. If you fix a 40 hour week your boss is disappointed that you stop working at 40 hours. If you do not have a fixed amount of hours your boss will still be disappointed, but you have no good reason to ever stop working. Without the 40 hour limit you work more and more and more and still disappoint your boss. The disappointment can't be avoided. But the unlimited overtime can be avoided, by limiting the amount of hours you work.
