An action taken to prevent or undo the effect of a previous action is often referred to as a "mitigation" or "remedial" action. For instance, if a company releases a flawed product, it may issue a recall to prevent further sales and mitigate potential harm to consumers. This corrective measure aims to address the negative consequences of the initial action and restore trust with stakeholders.
The idiom "put an end to" means to stop or terminate something, often referring to a situation, action, or event that is undesirable or ongoing. It implies a decisive action taken to conclude or eliminate whatever is causing concern or difficulty. For example, one might say, "The new policy aims to put an end to unfair practices in the workplace."
