Employment is a very basic economic trade. You trade your time and effort in exchange for money and benefits given to you by an employer. It is that simple.
You do not work unless you value the money and benefits you receive higher than you do your time and effort, just as you don't buy a can of beans unless you value the food higher than you value the money you exchange for it. You get to choose exactly how much you value your end of the exchange.
The other party to the exchange gets to choose how much they value their money, when compared to the amount of labour they are willing to receive in exchange for giving that money away. It is that simple.
In order to be employed, and remain employed, you must provide enough utility to another person to encourage them to give up their money. And you must offer greater utility than those competing for the same money.
If you are unable to provide value to the market, or you believe the market values your time and effort less than you do, then you are free to do other things with your time and labour. Alternatively, you could increase your utility, offer greater value to the market for a greater price, or move to somewhere else where you believe you may get a greater value for your time and effort.
But this is a very basic and simple economic exchange, and provided the employer is content with the employee(s) he gets in exchange for how much he is willing to pay, he is absolutely spot on with his valuation of his money.
Of course, if he is wrong, he will have no employees, and his business will collapse. That is how a market economy works.
