But for how long will you remain indispensable, it will only take some time before someone or a machine is able to do the job you do for the company, and your position becomes threatened.
Understanding and knowing that there is every possibility to be laid of work should make you not want to avoid the corporate environment of work but make you want to plan better with every income you earn from working there knowing that It is not permanent and the earlier you are able to set up yourself individually either as a business person or increase the opportunity you have, the better for you. You should never be relaxed when you are working for someone because you do not own the company and it is not a government job where there is more job assurance.
