what about sick days?
As someone mentioned above, you really are an 'ignorant tool.' :).
Sick days? If you are sick you don't take any projects (and if you have any projects already assigned they will be reassigned if you let the admin know).
they are the base and source of revenue in your organization, but... they don't have any power.
They have all the power. Working as an independent contractor they are not controlled in any way, they can work anywhere, however, and whenever they want, they even set their own bids on some websites.
If they don't like the company one day? - they use their power and stop taking projects from them. To show even more power they could take a 100 dissertation and not complete it to bring financial and reputation loss to the company.
I know at least two cases when freelance writers started their own companies and websites to directly compete with the 'parent' companies because the 'parent' companies were giving them direct emails of their clients to communicate. That's how they used their power, but that's how the industry works - writers are in direct competition with the companies (only email is needed in order to establish direct competition). To my knowledge they still have accounts with the 'parent' companies because they couldn't afford the costs of their own advertising and other headaches.
the owner takes home a couple of hundred grand, and the writer takes home maybe thirty or forty.
You've just come back from the Moon? The proportion - if it's true - compared to other industries is still very reasonable. Check the average proportion of the American industry - why don't you sign up at WallStreetForum.com or similar to preach your gibberish.

All your posts clearly indicate you have never worked in the private sector. I don't understand why you are wasting the taxpayers money posting nonsense on this forum.
