农民工作为一个流动的社会群体,已经成为了中国产业工人的重要组成部分。然而他们的“权利缺失”和“权利剥夺”状态却尤为明显,他们的利益时常被损害却没有一个有效的利益表达机制,因而给社会稳定带来了严重的挑战。尽管自2003年以来,全国总工会和各地工会加强了吸纳农民工加入工会的力度,但是,仍然有大量的农民工因为种种原因游离在工会之外。对影响和制约农民工加入工会的因素进行分析和梳理有助于我们厘清传统工会的改革方向。 Migrant workers, as a mobile social group, have become an important part of China’s industrial workers. However, their “loss of rights” and “deprivation of rights” status are especially obvious. Their interests are often damaged without an effective interest expression mechanism, which poses a serious challenge to social stability. Although since the All-China Federation of Trade Unions and local trade unions stepped up their efforts to attract migrant workers to trade unions, a large number of migrant workers still remain outside the trade unions for various reasons. Analyzing and combing the factors that affect and restrict the participation of migrant workers in trade unions helps us clarify the reform direction of traditional trade unions.
