An administrative assistant is someone who helps other people in a company, like a boss or manager, with tasks that could be hard or time-consuming for them to do by themselves.
Just like how you might ask a friend or family member for help with something, like picking up your toys or getting dressed, a boss might ask an administrative assistant for help with things like making phone calls, sending emails, scheduling meetings, filing papers, or organizing documents.
The administrative assistant is like a helper who makes the boss's job easier by taking care of some of the small details or tasks that need to be done. Just like how you might make your friend or family member's day better by helping them, an administrative assistant can make their boss's day better by helping them be more organized and efficient.
