工会密度的核心原因一直在美国以及加拿大的下降是因为在1980年和1990年的公司已经开始协调一致以及广泛的攻击工会和一些政府官员也贿赂的劳动法,使公司更容易防止工人繁荣(罗斯 & Chaison 1996)。下面是分析美国和加拿大之间的联合密度差。
The Trade Union density in both the US as well as Canada has always been on a downward spiral in the last few years. According to several statistics, the private sector union membership of Canada was almost 35% in the early 80s and 90s, but by the start of the 21s century it had declined by more than 18%. Similar situation was going on in the US in that era. Trade Union membership had fallen down to 8% in 2002, from an astounding 29% in the 1985 (Farber, 2005). However there are several reasons which have contributed to the ever continuing decline in the private as well as public sector union membership. They include the continuing loss in the manufacturing as well as the industrial sector due to out-shoring, fierce global competition, downsizing due to advancement in science and technology.
The core reason why the union density has always been on a decline in the USA as well as Canada is because during the 1980’s and 1990’s corporations had begun a concerted as well as a widespread assault on trade unions and some of the government officials were also bribed for in labour laws which had made it much easier for companies to prevent workers from flourishing (Rose & Chaison, 1996). Below is the analysis of difference of Union density between USA and Canada.
