Yes, but you presume that single worker working 40h&#x2F;w will charge you the same hourly rate as the one working just 15h&#x2F;week. It very much depends on peoples&#x27; own perception of how much work is &quot;normal&quot;, and if you ask them to work more then the usual norm they&#x27;ll probably ask to be better paid  (per hour) for extra effort. Which would make them more expensive to hire, which would lead to hiring more 15h&#x2F;w workers... some sort of equilibrium would surely arise, but only for jobs that are in high demand... unqualified workers will only work more and more...
