What does it mean for an action to be illegal in the context of strikes?

An action is considered illegal in the context of strikes when it does not have prior notice. This means that the employees or union leading the strike did not inform the employer in advance, which is often a legal requirement. Many countries have labor laws that stipulate certain protocols for striking, including the necessity to provide notice to the employer. This notice period allows for negotiation and the opportunity to resolve disputes without disrupting the workplace.

In contrast, a strike that is approved by management or conducted with a public vote is generally considered lawful, as these indicate some level of agreement or adherence to regulations. Likewise, support from a majority of employees often signifies that the strike has legitimacy and backing, making it less likely to be viewed as illegal. Therefore, the absence of prior notice is a critical factor that can render a strike illegal.
