The Employment Relations (Northern Ireland) Order 1999 (Blacklists) Regulations (Northern Ireland) 2014
These Regulations generally prohibit the compilation, use, sale or supply of blacklists containing details of trade union members and activists, where the purpose of that list is to discriminate against workers on grounds of trade union membership or trade union activities (regulation 3). The Regulations give rights to persons to complain to the industrial tribunal in certain circumstances. These rights arise where a person has been refused employment (regulation 5) or employment agency services (regulation 6) or has been subjected to a detriment (regulation 9) for a reason related to a blacklist.
