 For the most of the latter half of the 20th Century, trade unions enjoyed relatively stable and secure positions within the country's consensus-oriented industrial relations system.However, following the recession of the early 1990s, trade unions came under increasing pressure from employers and the government which promoted the deregulation of labour markets, less binding collective bargaining and weaker wage growth.At present, there are two national trade union centres; the Swiss Trade Union Federation (SGB/USS) with approximately 385,000 members and Travail.Suisse with approximately 170,000 members.
