Doctors, lawyers, engineers, managers....anybody with a job title that
is remotely "professional" sounding is paid a fixed salary, which if
you want means they work for "free" if they work beyond 40 hours.
Though I hear that even WalMart clerks are called "Associates" or
something and management tries to get unpaid work from them.
