Salting

Salting is where labor union members hire on at a non-union business and assess workplace satisfaction and interest in organizing a union. US labor law prohibits unions from talking with workers in the workplace, and salting is one of the few legal strategies left that allow union organizers to talk with workers.

Once worker interest in organizing is determined to be sufficient, all workers will be housecalled at home (since they cannot be contacted at work) and a meeting will be called with the purpose of forming an Organizing Committee if there is sufficient interest. A card drive will then commence, and once a majority of workers sign cards, the NLRB will be contacted and a date for an election set. Without salting, organizers are at a distinct disadvantage because they have no way to assess a workplace or contact workers.
