Answer: Blacklisting
Explanation:
When an employer or a person with the power to blacklist, blacklists a person, it serves a warning to other employers in the industry not to hire the person in question.
Blacklisted people are therefore denied work, opportunities, access or recognition which is why when a person is blacklisted, their career is virtually over.
