blacklist
Concerted action by employers to deny employment to someone suspected of unacceptable opinions or behavior. For example, individual workers suspected of favoring labor unions have often been blacklisted by all the employers in a region.
‡ During the McCarthy era (see Joseph P. McCarthy) in the 1950s, the careers of many public figures suspected of communist activities were ruined by blacklisting.
