I joined a department wherein we don't call our Manager any honorific names e.g. Ma'am, Miss, and even "po" (I think it was only implemented inside our department). We call each other after our first name, no use of sir, boss, ma'am, kuya, ate, and such honorific names. It feels like they are your friends, which makes the workplace culture very pleasant.

Cons in my department are very minimal, maybe in other department.
