In the warehouse, Ryan suggests an assembly line to make things more efficient, and Stanley firmly corrects him that they're running out the clock. "Just like upstairs." I think we just learned more about Stanley than Michael has assumed about him in the entire series run.
Jan is going over commonly-used sports metaphors, because guys use them in the office and chicks don't get them. While Pam tunes out by drawing her house with the terrace, Kelly innocently asks what "second base" means, in the context of Michael having said he got to second base with Jan. Jan gets flustered and acts like she doesn't know what Kelly's talking about. Kelly secretly tips the secondary camera a wink.
Meanwhile, Pam excuses herself when she sees Jim outside the room, checking his voice mail. "We watched a video about our changing bodies," she deadpans so effectively that Jim almost believes her for a minute. She tells Jim about the design thing, which Jim thinks is a great idea.
So how is Michael doing with the union-busting in the warehouse? Well, we see him throwing several cubic yards of Styrofoam packing peanuts into the industrial fan so he can pretend it's snowing. "You ever do this?" he asks Darryl. It's apparent from Darryl's face that he's thinking about a famous movie scene that also has snow and whirling blades, and that scene is from Fargo.
The women have finally turned on Jan, quizzing about her divorce and, in Kelly's case, why she "did that thing with Michael." Jan calls a break.
She goes down to the warehouse and asks Michael if he's "taken care of it" yet. He lies, badly that he has. So without even coming all the way down the steps to the warehouse floor, Jan takes control of the room and announces in no uncertain terms that unionizing is a really bad idea. It killed the Pittsfield branch, and if they even think about it here, they'll be screwed. If they have any more questions, they can ask Michael, who is now hiding. Jan leaves, invigorated. Because why deal with the fallout from the worst move of your romantic life (so far) when you can go crush an insurrection single-handedly instead?
