Why do many companies dismiss employees who seem to be diligent?

I don't know if you have found out that many employees dismissed by the company have one thing in common, that is, employees who seem to be very diligent. So why on earth is this? Aren't hard-working people popular with many people? No matter at home, at school, or in other places, diligent people are particularly popular with everyone, but after leaving society, diligent people seem to be rejected. So what are the reasons why those employees who seem to be diligent are dismissed by the company? Let's talk about those employees who seem to be diligent this time.

Diligent but incompetent.

The company recruits employees to solve problems and create more benefits for the company, but some diligent employees have poor working ability. Even if they are diligent, their performance is still at the bottom, or they can't meet the requirements of the company at all. The company is not a charity or a school. It has no obligation to spend so much money to train an employee, and it has no time to wait for the employee to grow up slowly. Therefore, to enter the society, we should understand that society is cruel, only the fittest survive and the weak are eliminated. Therefore, no matter how diligent employees are, they can't create benefits and can only be dismissed by the company.

Hard-working but inefficient

Some employees are usually diligent. They are the first to work in the company, and the last to leave the company. They are never idle during their working hours. Such employees seem to be diligent, but they are inefficient. Usually this kind of workload can be completed by others in one hour, but some employees need to double the time to complete it, and the work of the day needs to be completed the next day. Such an inefficient employee, no matter how diligent, is also a waste of company resources.

False diligence is actually just flattery.

I believe that we often see some people in the workplace who pretend to be busy when the leader comes, but secretly they are cheating and flattering the leader. Such people will only be the black sheep of the company and destroy the atmosphere of the whole company. People who can become leaders are not brainless, so leaders have eyes. When the company needs to lay off employees, it will definitely lay off these people first.
