Final answer:
It is generally acceptable to open a locked door for your boss provided that you have the proper authority and there are no policies that forbid it. You must consider both the business etiquette and security policies of your workplace before acting. The correct option is B.
Step-by-step explanation:
The question of whether it is acceptable to open a locked door to let your boss in a building can be considered from both a business etiquette and security perspective.
Generally speaking, if you have the authority and the means to open the door (like a key or access code) and there are no company policies or security protocols that forbid such an action, it is typically acceptable to do so. However, this action should always be aligned with the company's policy and security measures.
Your relationship with your supervisor is indeed important and can influence your career, as they can provide opportunities or restrict them.
It's essential to understand that being helpful and demonstrating initiative by opening a door for your boss can be perceived positively. That said, you must also ensure that your actions do not compromise the security or violate any policies in place. The correct option is B.
