When can an employer check the number of trade union members?

From the employer’s point of view, the request to be involved as a participant in the proceedings to determine the number of trade union members is the most important one. It allows the employer to attend hearings, submit requests for evidence, and receive access to the proceedings’ files. This is regardless of whether the objections were submitted by the employer or another trade union, or whether the proceedings were started on the basis trade union’s own request. – Sławomir Paruch and Robert Stępień comment for Rzeczpospolita.
