The Consulting Association (TCA) was a controversial UK business (described by its key figure as "a non-profit making, unincorporated trade association"), based in Droitwich, which, from 1993 to 2009, maintained a database of British construction workers and became implicated in a "blacklisting" scandal, which is ongoing. Revelations about the database resulted in the business being shut down, the Employment Relations Act 1999 (Blacklists) Regulations 2010, a Parliamentary enquiry, High Court actions leading to compensation payouts valued at between £50m and £250m in total, and a series of cases being brought to the European Court of Human Rights.
