The strategy to avoid union salts is rather simple. But, simplicity does not mean easy. The process requires discipline. A salt is a paid union organizer that attempts to gain employment with a non-union employer for the purpose of either (a) organizing the employers workforce or (b) bringing a costly unfair labor practice charge for discriminatory hiring practices.
A “covert salt” is someone who conceals his union affiliation in order to gain employment with a non-union employer for the purpose of starting a union organizing campaign. Actually, conceal is an understatement. Covert salts actively lie to gain employment with a non-union employer. Covert salts apply for jobs under false names, social security numbers, and use bogus resumes.
