Prolonged protest is often referred to as a "sustained protest" or "prolonged demonstration." In some contexts, it may also be called a "sit-in" if it involves occupying a space for an extended period or "ongoing activism" if it encompasses a broader range of actions over time. These protests typically aim to draw attention to specific issues and maintain pressure on authorities or decision-makers.
