नात्यर्थमर्थार्थनया धीमानुद्वेजयेज्जनम् ।
A wise man will not press his employees too much in order to earn a lot of profits. He will do just enough to keep them motivated. When the Gods and Demons churned the ocean, the ocean first gave the divine horse (ucchaishravas), the lot of gems, then Goddess Lakshmi. Still they continued to churn. Hence the ocean gave them poison (halaahala).
PS: The real order of what the ocean offered during the churning is not accurate in the verse above. But it is only indicative of how a servant's response will be if he is demanded to work beyond reasonable times.
