The Right Way is a benefit to all and would make everyone happy so long as they follow it. When the path is not followed suffering is a given. The Buddha did not own a home or have employees, so by avoiding the problem suffering is prevented. For the businessman, he is caught on all sides by suffering, if he fires the employee, the employee may try to sue him, if he keeps the employee, his business may suffer. After a while of suffering perhaps Buddhism will start to look more attractive.

There is nothing I would change in your statement, it is a good enough principle to live by, although happiness is subjective and it is impossible to please everyone, so your statement is good for groups, but the most important things is everyone being happy individually by their own means. But that dramatically changes your statement around.

Only by your own means can you gain liberation, who else can do it for you?

As for your business situation, if firing a person would make the majority happy, then it should be done, just don't assume this will make everyone happy, because the fired party may not be happy. On the other hand if they don't like their job they may enjoy being fired, especially if the only way they can get unemployment is to be fired and not quit. People do strange things when money is at stake.
