You are working a long shift and notice your back is starting to ache from repeated lifting. What is the BEST action?

Mail handler injuries — especially back injuries from improper lifting — are a major operational concern at USPS and a heavily screened trait. The exam is testing whether you: (1) recognize body signals as feedback, not as something to ignore; (2) take corrective action (check technique, team-lift, brief rest); (3) communicate with supervisors when pain is significant rather than hiding it; (4) don't try to power through in ways that lead to serious injury. 'Push through' is the response pattern most likely to result in workers comp claims and long-term injuries — exactly what USPS is screening to avoid. 'Stop without telling anyone' fails because it leaves your team short. 'Lift faster' makes injury more likely. The right answer combines awareness + technique check + appropriate communication.
