Taken seriously - I’m not sure. That being said; in my experience taking the time to help others out ended up with those teammates and their/my manager(s) talking positively about me, which ended up working out well for me career-progression-wise. There may have been other factors at play but being seen as nice/friendly (and smart) and being liked really goes a long way.
