If while you're introducing the characters individually they make mention or know that there's a meeting at the end of the day, that may be enough.
It could be (this is terrible, but just to show you what I mean):
-------------
Homophobic Joe getting told he's being demoted from corporate to floor level because there are people who aren't comfortable with how homophobic he is.
Flamboyant Tim getting told he's being promoted.
Sarah the loose slut being moved because she's slept with every dude in her department.
Virginal Alice finally getting the job she's always wanted.
Main Guy Rico being told that he's getting his first shot at running a team and if he does it well he's on his way to VP level.
They meet, they're all different and decide they can't work together.
Rico's big speech tying the rag-tag team together.
-------------
I'm just using that as an example of how there's a loose "story" that ties it together so that the scenes we see before are necessary and make sense.
