At the end of your shift, your replacement has not arrived and your supervisor asks you to stay an extra hour due to a staff shortage. You have personal plans for the evening. What is the BEST response?

PROFESSIONAL RESPONSE TO OVERTIME REQUESTS tests integrity, communication, and team orientation. The BEST RESPONSE balances organizational needs against personal rights and obligations. KEY PRINCIPLES: HONESTY IS FUNDAMENTAL: if you have a genuine conflict (childcare, medical appointment, prior commitment you cannot change), say so clearly — don't say yes and then leave; don't simply walk out without explanation; PERSONAL OBLIGATIONS ARE LEGITIMATE: employees are not obligated to work unlimited overtime (union contracts typically govern overtime requirements in USPS settings; fair labor standards also apply); having personal plans is valid; ORGANIZATIONAL NEEDS ARE REAL: mail processing cannot simply stop because one person's shift ended; the supervisor is asking, not demanding (unless contractual requirements exist); cooperating when you can is a sign of team orientation; PROFESSIONAL FRAMING: 'I have a childcare obligation I cannot move, but I can stay 30 minutes while you arrange coverage' is a better response than either 'No' or silent departure. WHAT NEVER TO DO: agree and then leave prematurely — this is dishonest and leaves a critical gap without warning; argue about operational planning — the immediate situation is not the time for that feedback; be aggressive — supervisors have legitimate authority to ask for overtime. UNION CONSIDERATION: USPS employees are typically covered by collective bargaining agreements (APWU, NALC, NPMHU depending on craft) which govern overtime requirements and rights; new employees should familiarize themselves with applicable contract terms.
