Would you ever do your job for free, if you still had your needs met?

I'm trying to figure out what sort of role money really plays in society, and whether it's necessary. Although it appears on the surface to create freedom, enable advancement and reward effort, it can also be seen to do the opposite. It limits the freedom of poor people, by acting as a barrier between them and their needs and abilities. It limits advances in technology and science, because people strive to make maximum profit, so low quality, short lived goods are produced instead of putting expensive research into durable and innovative goods. As for rewarding effort, this question serves to ascertain whether it truly applies, although it seems that the jobs requiring the most effort usually get the least pay. A theoretical society without money would distribute resources to all people, regardless of their job, but would still require work to be done. So my question does have a conditional... In such a society, would your job still exist, and if so, would you still do it without pay, as long as you still get all your needs met?
