TEAM is another way to say "Everybody but me." It's popular in corporate environments where an asshole wants work done, but doesn't want to do it, but wants to seem like they want to. Therefore they start their email with "TEAM"
Being a team means being committed to something and sticking to it. It means even when you feel sick, depressed, or you have plans, you still participate and stay committed. No skipping. No 'Wahh, I don't fell good." No "I'd rather hang out with my boyfriend." All in all, TEAM means staying committed, showing up even when you don't want to, and giving all you've got. If you aren't willing to do that, they don't bother being part of a team.
Pajama casual is a term used when working from home and preparing for a video conference. All business above the waist and your pajama pants down below.
We have a Zoom meeting in a few minutes and I’ll probably go pajama casual.
