Teaching is the most developed job currently, but even it is not super far along. Right now they're mostly placeholders. It SOUNDS like GC has plans on putting some stuff in like office drama, fucking the boss at work, etc., but it's not implemented yet.
And like the guy above me said, the teaching job is... confusing. With the broken english and stuff it's kinda hard to tell what you're supposed to be doing. I've had weeks where I did literally nothing, like I forgot to go to work completely until the last day, and my students failed their tests but discipline was like, ungodly good? And I got a huge bonus for having such a well-disciplined class. I've had other weeks when I'm there every day, doing my best to teach them (both in a single subject that I'm highly interested in, and a broad range of subjects), and I get my ass chewed by the boss for being so horrible at my job. So I... really can't offer any advice on how to progress, lol.
