Each company has shareholders, directors, employees, and usually (but not always) a company secretary.
The company secretary represents the directors in matters regarding the statutory authorities and compliance issues.
Most companies also have employees, who work for the company. As well as being a director and a shareholder, you will also be an employee of the company. You may also choose to employ someone else to take care of day to day personal administration, and it might be appropriate to employ your partner or spouse for this purpose.
