Actually "commodity" professions actually have it pretty good on this score. By definition, commodity profession jobs are everywhere, because there are a lot of them, that's what makes them "commodity" - there are cashier jobs within a kilometre of where most of us live, as an example. It's when you start getting specialised that it gets harder to negotiate where you work - there might only be one company doing web-development work in a 10km radius around your home. Of course specialisation allows you to negotiate up your salary, so you can offset the loss of freedom in choosing the location of your workplace with an increase in freedom of choosing the location of your house / apartment due to a higher salary.
