> I can assure you that when I was young, I did not listen to older people's advice and I tried to do everything my own way.

Hot take: This reads like a person who was difficult to work with.

Senior people have responsibility, therefore in a business situation they have authority. Junior people who think they know it all don't like this. If there's a disagreement between a senior person and a junior person about something, they should, of course, listen to each other respectfully. If that's not happening, then one of them is not being a good employee. But if they are, then the supervisor makes the final call.
