As a lifelong Peanuts reader, I was absolutely tickled to see Schulz handling adult situations like this. No 'whomp-whomp' trombone sound from the cartoons, or offsite adults regularly alluded to in the 50's-60's (etc) comics, just ALL ADULTS.
Like, whoa...
And... of course this one ("Woman Boss") was not very nice, altho containing of some humor, perhaps. But really, that could be said about loads of his style, so what am I bitching about, anyway?
Back to the point-- "Hagemeyer" was a test by Schulz in the mid-50's to branch to a different style. There are, if I understand correctly, seven total strips, none of them published. I don't know the intended order whatsoever, but this is my best-effort to post this one in decent quality.
In terms of other strips Schulz did, check this out:

Okay.
