These are the basic roles in a business. Pick one of these if you want a business job.
- CEO or President
The roles in this category are transferable amongst various businesses.
Some roles are more for larger companies, but some roles can be found at even the smallest companies.
The smallest company might be an independent contractor. And even he or she needs to interact with a lawyer, accountant, sales, and IT or do it on their own.
Of these, it seems that law would be the most difficult to do on their own.
If you choose a role in one of these fields, then you can transfer between companies. You can offer skills you gained in one company to other companies. You can freelance and more easily state your value.
My role for my job is more specialized. Probably only a few companies would understand it, it is not standardized across companies, but it would be valuable to the ones that want it.
That is another route.
But it is not as transferrable.
