Step-by-step explanation:
When a supervisor says 'leave your stuff at the door,' they are instructing you to set aside personal issues, concerns, or distractions before entering the workplace. This is a metaphorical expression asking employees to focus solely on their work and not let personal matters interfere with professional responsibilities. Complying with this request often involves maintaining a professional appearance, treating everyone with respect, completing tasks within the specified time, and demonstrating support for the company's overall goals. It's a reminder that while at work, one's full attention and commitment are expected, and outside distractions should be minimized to maintain productivity and a professional work environment.
