Robots Inc has lawfully locked out its unionized factory workers after exhausting negotiation and conciliation procedures prescribed by the applicable labour relations statute. Despite the lockout, Robots Inc has been able to continue supplying machinery to large automotive manufacturers, largely through accumulated inventory. These car makers are the biggest customers of Robots Inc. The workers are furious that they have been locked out, because they thought that their position during negotiations was quite reasonable. They are also getting desperate because they have been locked out for six months and are facing severe financial hardship. Picketing has not proven effective in getting media attention or in pressuring Robots Inc to come back to the negotiating table. The workers want to get their message out and want to get media attention to their plight. However, they want to do so in a lawful manner. What course of action would you suggest?
