Can only speak for myself, but I also work for a fairly large retail company (lowest of the low men on the totem pole, barely made it on, honestly), and I try to keep my company name out of my social media.

It's not really about respecting the company, it's a sort of the principle of the thing kinda deal. Hard to explain.

If I get fired, it's a different story, (like when Pizza Slut used no call no shows to fire me even though they couldn't give me specific examples).
