Tired of being ‘the new guy’ despite having been here 2 years
In most places, after 2 years, you are the expert.
If you are tired, quit.
Then no one would know how anything works. You know not what you speak of. Definitely sounds like a new guy.
Take advantage of "being the new guy" to take your sweet time doing anything that someone else asks you to do. Unless you're out to create an empire from day 1, I don't know how being the new guy is tiring.
Such a privileged problem
