Can workers be blacklisted for their membership of trade unions?


What is meant by blacklisting?

The process of blacklisting occurs in the employment sector where employers make a decision that they do not wish to employ anyone who is a member of a trade union. Blacklisting is not simply in relation to trade union membership, there can be other factors involved, but the most common factor is due to trade union membership.

Why would employers not wish to employ individuals who are members of trade unions?

Employers may not wish to employ individuals who are members of trade unions as they may believe that some of their employment practices may come more under the microscope and they may be more liable to industrial action.

Often employers will ask potential employees to go through a vetting scheme whereby they ask questions prior to interviews. Some of these questions can relate to membership of trade unions. Often if it is found that an individual is a member of a trade union then they will blacklist them from employment with that company.

The most common way, however, in which employers will become aware of potential employees’ membership of trade unions, is through individuals accessing databases providing details of trade union membership and then selling these on to companies.
