There has been a steady decline in unionization, from 64.4% of employees in 1993 to 30% in 1999 and then to 17.3% in 2009 (Myant, 2010, Visser, 2013). However, the percentage of employees covered by collective bargaining is higher, estimated to be at least 30% but possibly as much as 41% (Myant, 2013, Visser, 2013). Nominal wage increases achieved through collective bargaining agreements have broadly mirrored aggregate wage growth in the business sector since 2010 (Table 2.4).
