Why are many bosses unwilling to recruit healthy and hard-working middle-aged people aged 40 to 55 as employees?

In all kinds of resumes we read, the requirements for age are relatively high. For those hotel service personnel, their requirements are mostly under 45 years old. But for some companies, they are more suitable for experienced young people under the age of 35. So why don't many bosses want to recruit healthy middle-aged people aged 40 to 50 as employees?

The first point is of course physical strength. For a 40-year-old middle-aged man, although he still has some physical strength, he may be much worse than a boy in his twenties. Moreover, many units require overtime, which is a great test for energy and physical strength. For young people in their twenties, they can still be alive and kicking after a day and a night, but for people in their forties, staying up all night may stop eating at all.

The second point is the burden from the family. People over the age of 40 have become parents, which can be said to be old and young. For such a state, their families have a heavier burden and many things. Whether the elderly are sick or the children are sick, they need to be taken care of, which will of course delay their work. After all, the boss's company is not a charity enterprise. Of course, we should try our best to avoid such a situation.

The other is the cultural level. For people over 40, high school level is good enough. I know that nine out of ten people walking in the street today have college education or above, and many undergraduates are still unemployed. The boss left these highly educated young people, why did he use those in their 40 s?

In addition, there are reasons for the population base. People aged 40 and 50 are at least two brothers, so there are many people but few jobs, so the competition is fierce. For people of their age, they want to be more stable and don't want to work far from home. Therefore, although people over the age of 40 are hard-working, not picky about their work, not demanding about their wages, not too dirty and not too tired, these advantages do not seem to stand out in the face of these realities.
