Sorry, just making the point that when you go self employed from a salaried position, you must know you will lose some benefits/employment rights but the other side of the coin is you are in charge and if your business does well you reap those benefits rather than share them.
To an extent, it's personal choice. I left a salaried job in London and am now self employed but I wouldn't ordinarily expect the Government to cover my sick pay, holiday pay etc.
No you don’t expect those benefits because you set your own rates/tariffs. Concerning a successful business though you pay your tax on this so I see no particular benefit other than you reap what you sow.
