5. Your co-worker has some personal business to attend to at lunch that he knows will take him more than one hour. He has asked you to cover for him if the boss starts looking for him before he gets back.

It's important to consider your own boundaries and responsibilities before agreeing to cover for your co-worker. If covering for them will not negatively impact your own work or schedule, you can consider helping them out. However, if it will put you in a difficult position or prevent you from completing your own tasks, it's okay to politely decline and suggest alternative solutions, such as informing the boss beforehand or rescheduling the personal business. Remember to prioritize your own work and well-being before agreeing to help others.
