What does an “open door” policy mean to you?

Sir, this means that the door of every manager is open to every employee. This enables employees to openly clear their queries, problems, discussions, feedback, etc., with the manager and vice versa. I have always been one of the people to whom my team members can reach out for any concern, and I always try my best to answer their queries. In case I am stuck with some other urgent work, or I cannot answer them with the right approach, I assign them to the other experienced people in the company and ensure to follow up on the task's progress.
