THE CONDUCT OF INDUSTRIAL DISPUTES
An enduring feature of strike action is that those who are engaged in it will seek to persuade others to support them or join them so as to enhance the effectiveness of the strike. This is known as picketing and, historically, has been an established feature of the conduct of industrial disputes in Britain. Picketing may have several objectives. It may be intended to persuade workers not on strike to join the dispute or to discourage or prevent substitute labour from attending the workplace. Alternatively, the object may be to disrupt the supply of goods and services to the workplace by, for example, asking lorry drivers not to pass the picket line and deliver to the employer. Where secondary picketing takes place, employees involved in the primary dispute picket other places of work; usually to encourage those workers to join them on strike so as to cut off the supply of goods and services to the primary employer.2 A secondary ‘information picket’ may merely aim to publicise the dispute rather than actively disrupt economic activity at the workplace.
