At the end of a round, do Hiring spaces refill to three Workers, or does each short space gain just one?

Question

Accepted Answer

Each Hiring space with fewer than three Workers gains just one random Worker from the bag, not a refill to three. The designers made this change to keep game length more predictable and even out turn counts. Some campaign videos show the older refill-to-three rule, and the publisher advises against it.
