A job is not something you are entitled to. A job is not something an employer is, or should be, required to provide for you, whether you are competent or not.
Simply, a job is your selling of your time and skills to someone else for renumeration. What you receive for your time and skills is the result of the demand/supply equilibrium for whatever you do based on competition and scarcity.
Therefore, whether you realize it or not, if you have a job you are actually self-employed.
If your services are worth more than your employer is paying, then you should be able to leave your job and make as much working for yourself. If not, you are overemployed. Enjoy it, because it will not last.
If you would prefer not to be self-employed, become a civil servant or tenured professor. Everyone else is subject to the basic realities of global economics whether they like it or not.
