Before the change, Postmates paid workers a base rate per job, plus a per-minute rate for wait time and a per-mile rate for miles driven between the restaurant and the customer. If that didn’t add up to a “minimum guarantee” of at least $4 per job, Postmates had to make up the difference.

And overnight, they’ve rolled out a new pay model that cuts base rates and per-mile rates in most cities — oh, and they’ve gotten rid of that “guaranteed minimum” per job too.

That minimum was already low — $4 per delivery isn’t much when you have to cover all your own expenses. So the fact that Postmates is getting rid of it tells us their new pay model is all about going lower than low.
