Plans to change the law so public sector workers including nurses and rail workers can be sacked for going on strike could have "unintended consequences" of provoking further conflict, MPs have been told.
The Transport Select Committee questioned rail industry and union leaders about plans to legislate for minimum levels of service during rail strikes, which are currently going through Parliament.
Jamie Burles, managing director of Abellio Greater Anglia said the "overriding" objective of the industry was to avoid strikes and have good industrial relations.
