Yes. Companies having that choice is also interesting in that they get to decide if it's worth to have people come and go, as a replaceable resource. For some company it totally works and they plan their staffing in 6 months spans (seen a small web agency basically having an "on" and "off" season, with half of the staff during the dead part), removing or adding people as they see fit. For others it's more difficult and they're pretty happy to have staff that can't just disappear within a month if they decide to go tour the Silk Road on a bike.
