1, the management of the enterprise
Your father has done business after all, if it is a big business, then his management ability should be good. Therefore, he can relocate his experience to other business management jobs. After losing his job, your dad can continue to work in the business as well.
In fact, although he is fifty years old, if he is an executive, that age is not too old. Of course, at his age, he's going to have to learn to use his contacts to get a job, instead of submitting resumes for another job!
2. Do what he's good at
You need to ask your dad to see what he's good at. For example, is he good at writing? If he is good at it, he can do the self-publishing, although the self-publishing salary is not high, but he has so many years of work experience, if he can share it, it must be able to help a lot of people.
3, do the work he is interested in
After all, he is already fifty years old, if he really can't find a suitable job, then do the work he is interested in. For example, if he wants to do the job of a security guard, then let him do it.
In fact, when you get older, you may not be as enterprising. The next step is to do what can be done.
4. Do something simple
For example, jobs like janitorial and security can be easily done without work experience. Even if your dad doesn't have relevant work experience, he can still do it.
