The use of injunctions to stop or limit picketing during strikes had a significant and negative impact on unionization by turning public support away from unions and demoralizing strikers.

The use of injunctions was a tactic used by employers to limit the effectiveness of strikes by preventing picketing and other forms of union activity. However, this often backfired as it turned public opinion against the employers and the government, and made many workers more sympathetic to the strikers and their cause. Injunctions also had a demoralizing effect on workers, who felt that their rights were being violated and that they were unfairly targeted by powerful interests. This, in turn, made it more difficult for unions to organize and mobilize workers in support of their interests, thereby limiting the impact of their collective bargaining power.
