‘Men are in the habit of taking an erroneous view of what they may be permitted to do in the shape of picketing.’
Throughout its history, the law on picketing has been a matter ofdispute between those who see any interference with an employer’s ability to carry on his business as wrongful, and those who see picketing as an essential and lawful part of that collective strength which is a prerequisite of effective bargaining. Sometimes the issue is seen as one of industrial relations, sometimes as one of civil liabilities and sometimes as one ofeconomic theory, but in the event the resolution of the debate has been mostly political. Over the past 170 years many attempts have been made to set the balance but a permanent answer cannot be achieved, since the economic and political considerations of each era will lead to a re-assessment of the appropriate balance.
