Just trying to put some reasonable bounds on this estimate. I assumed 12 weeks is "the holiday shopping season" where Amazon has a lot of extra workers who would benefit. And I guessed 250k of them getting $3 raises. You could also guess at the total cost in other ways, many of which would be superior.

The overall goal of these lazy estimates is to understand how significant a cost this is for a company like Amazon. Could activists have hoped for more? Are other companies, for whom the costs would be felt quite differently, likely to offer something similar?
