partnership can be a group of more than 1 people in a fix number. We call it partnership.
partnership shares everything, it means you, as a partner, has a pecentage of the company( even 1 % ). Everyone shares the profit, the building, the expeneses, loses...
Then you might ask, each partner has its own share. Then what is the company like Microsoft, Nortel.. if you own their stocks, you are part of the company too.. partnership is usally held by a fix number of founder, owner. and their shares are not buyable in the public.
If you just share your wisdom, and NOT part of the company.Then you are not a partner, you are just an employee. If the company is depends on your wisdom to operate, you are called an key employee.
