Please note I have used slightly modified job titles to describe this without showing who's behind the scene.
I work at an established corporate, and the head of my department (Marketing) was someone who I used to work with at another company before joining this one. At first, I was impressed by him as he successfully transitioned from project manager to head of marketing.
And then, I found out the uncanny truth a few days ago.
When I visited this guy's LinkedIn profile to give him kudos, I realized that he put a fake work history. He claimed to be a "Senior Marketer", "Principal marketer" while he didn't have any professional marketing experience at that time. His role back in the days was not related at all.
I mean, he is capable of his job as head of marketing, but... it seemed like he got the job with the fake work history. Maybe he wanted to add up more years of experience? I don't know why he did it, but I don't know how to approach it from now on. He is in charge of the entire marketing strategy of the company. I think he can still continue to work but morally this stresses me out.
I'm not sure what should I do to fix this, and what's the recommended action to take.
Any advice?
