I can never understand this 'employee' part - take this example...
I know of a good house painter. He has been recommended and I have seen his work at a friend's house. He could substitue other painters to do the work for him. I stipulate he will only get the work if he alone does the work, only him, him alone. We agree on a daily rate over a set period of time. He has clear deliverables, to paint my house.
Because I have stipulated only he himself may paint my house, do I now have a house painter on my books? Do I have to give him sick pay, maternity leave etc? Of course not.
If I choose the paint, the brushes and tell him I want the ceiling completed before the walls ..... is he my employee. Of course not.
If I pop in halfway through the job and check it is going to my satisfaction, is he my employee? If I notice some poor 'cutting in' and ask him to just go over it again is he my employee? Of course not.
At what stage would this bloke be my employee?
