get some blackmail on em
By realising, s/he may be your manager, but hes just a person, doing a job. Theres nothing special about him. And clearly, if your afraid of that person, then hes a crap manager with no people skills. Now is a person like that, who isnt approachable, worth being afraid of?
If he dislikes you and disrespects you for no reason then stop giving a f uck. They've shown you they don't care for you nor do they have respect so unless it's work related, f uck 'em.
I was afraid of my boss because I sought his approval but when he showed me how little he thought of me, I stopped caring. I did my work but I didn't cringe when he decided to confront me. I faced him head on instead of biting my tongue.
imagine him naked, eating a messy sandwich
You should not, if he/she is creating a hostile work environment, then you should report that to HR.
Unless of course you are always goofing off...
if you got a good reason to be afraid of him, turn him in
Get to know him/her better. People are often not as bad as they may seem.
Why are you afraid of?
Intimidated...maybe, but scared?
By realizing that fear will never benefit you.
Get a different job.
