Showing posts from specific user in Laravel

I have a question about showing posts from specific user. I'm building a basic keeping records website for my brothers company. I made a redirected login for normal users(workers in company) and for admin(company manager). So I'm new at Laravel and programming, a did everything for this website and all I need is how to show posts on admin profile for specific user. On admin profile I'll make pages for all workers profiles and on specific page I need to show posts for that specific user. How can I do that? Making new Controller?
