A contemporary approach that deals with major trends in the law of labour relations and discusses the reasons for the trends and their impact on the overall operation of collective bargaining. The authors provide economic analyses of the problems resulting from the efforts of government to define the rights, duties and obligations of labour unions and employers in the area of labour relations and collective bargaining and concentrate on the major developments including lawfulness of testing employees for drug and alcohol abuse, and union obligation to provide fair representation to its members.
