editor75,
Your ideas are not down to earth for sure. You list the things to make the writer's life better, but fail to answer one simple question "why would someone bother"?
Yes, writers are the main asset of a company, however there is no deficit of writers, far from it.
By offering to introduce "paid sick days" you compromise the whole point of freelancing, as this will inevitably make you account for your "sick days" as you would to your offline boss.
