An 80-strong group of Labour MPs has taken the unusual step of writing to shareholders in National Express to urge them to vote down its report and accounts at today's annual meeting over its treatment of drivers of US school buses. The letter...argues that the move is needed to "signal the necessity for improved oversight and reporting of human capital policies and practices". The letter says..."Over the past few years we have learned from National Express Group workers employed by the company's North American school bus subsidiaries and their union representatives of what we believe to be a systemic approach from the company to deny workers their rights to freedom of association and engage in collective bargaining for their working conditions,"...National Express says it has "robust policies" in place to guarantee workers' rights and that "reflecting the importance of employee relations, and in line with accepted practice, this issue is reported to the whole board".
