New hires and juniors can easily learn by taking an active part in their own education. Firing a question into a public slack channel waiting for someone to answer is the laziest attempt to actually get an answer. Better is identifying someone who can help you and asking them a question directly. Take the time on your own to figure out what it is you don't understand, make a list of questions, and ask them directly, or better yet, hop on a quick video meeting and ask. The most effective way to learn in person isn't any different. What you are describing is in fact the laziest way to learn, which is to try nothing on your own, and expect everyone else to tell you exactly what to do.

Requiring everyone to be in an office because your personal learning style involves no personal effort and requires everyone else to enable you to be effective is in fact selfish.
