So I've recently joined the company, and there is a guy who shares same position as me, but older than me by 7-8 years. Our boss is also young; same age as me.
So the coworker started picking on me. Like making disciplinary warnings such as "Why you were late for 10 minutes?", "Why do you go outside to smoke so often?", or "Why you going home so early, you got nothing to do left?" (when I go home on time).
My boss is an introverted guy and he doesn't care much because this coworker is more experienced than both of us.
But it started to irritate me as he is not my boss, but bossing me around.
Is there any way out of this?
