A tight labor market can be a factor here. For example, if one is looking for a job. But it can also be that it forces you to stay in a work environment where you don’t feel comfortable. Another social factor can be a high pressure to perform. In certain regions, for example, you may not be a person until you own your own home or playfully manage your professional life, club, and family. This also brings us to the third factor, unrealistic role models. This can be a woman who would very much like to work, but her upbringing and society demands that she, in addition to a successful career, also manages children and household without help. But it can also be a man who has learned to always be strong and to provide for the family financially. If he now loses his job or does not get a promotion, this favors a burn-out, because the self-esteem of this man sinks.
As you can see, there are many factors. Most of the time not only one factor triggers a burn-out, but a combination of several.
For example, it may not be bad for a person to always work under time pressure, but if there is a constant conflict at home and it is difficult for the person to say “no” in private, then this can have an impact. Just think of every possible combination of the different factors.
