Why did blacklisted union members have trouble finding jobs after the Pullman strike?

Blacklisting meant employers were warned not to hire union members who had participated in the Pullman strike. Other potential employers often saw these workers as troublemakers or as likely to organize labor disputes, making it difficult for them to find jobs. Blacklisting did not itself mean they had been arrested or could be criminally charged for applying elsewhere.
