Karol Sołtys’s aim in this article is to identify future threats in the area of collective disputes. He examines in detail three issues: the monopoly that trade unions have on organising strikes against the background of the low level of workers’ membership in trade unions; the employer’s passivity towards the possibility of the simultaneous organisation of numerous strikes in the workplace; the right to lockout. In view of the threats discussed in the article, it is necessary to open a debate in Polish labour law over the adoption of exceptions to the said trade unions’ monopoly on organising strikes. The debate should consider the possibility of a liberalisation of regulations concerning the representation of employees. In the context of employer protection, special attention should be paid to the right to retaliatory lockout.
