For the record, I've never worked anywhere that this was the case. I mean, yes, if you get hammered and act stupid, that's obviously going to impact your job (probably, unless you work in the kind of place where your boss is right there with you), but pretty much everywhere I've ever worked, people came if they felt like it, had a drink or two and some snacks, and not one person ever gave it another thought.

Caveat: I've worked for the government for my entire career. It might be different in more sociopathic industries.

The people who come up with this twisted corporate shit need to be banished from society forever

In my 20s, I always skipped the office holiday party. I love partying. I enjoy drinking. And a lot of my coworkers were young and attractive. I simply never heard of anything good coming out of that mix. Like: The risks (doing something foolish, losing respect) FAR outweigh the potential gains (flirting with someone? Or, maybe hooking up with them if you're really really discrete, but that felt unlikely in any of the places where our offices had parties.)

Ugh.
