Understanding your scope of responsibility is the first step to prevent being unfairly blamed. Consult the job distribution sheet or contract clauses to ascertain which duties are genuinely yours. When others attempt to sidestep their obligations onto you, you can articulate your stance clearly with these documents. For instance, if there's a problem with a project you're not part of, you could gently say: 'According to my understanding, this portion of the work was the responsibility of other teammates, maybe we should check on their progress first.'
