Employee vs employer

Never has an employee said:
Wah boss. You are so kind and generous to me! Even though the company may not make money, or sometimes when I don't give my best, you still pay my salary every month. You are such a great person! So for this month, I will give my best and you no need to pay me.

The boss thinks:
Employee ah employee! You are so kind and generous to me! By giving you some money you give your youthful years to me. You give me 5 days a week, while I give you 2 days off a week. You are too kind to me. I will continue paying you money (which is a small part of what the company earns) while you give me your time which you will never earned back, to make my dreams come true!
