Winnie,
The cleaner is an employee because you set the terms and conditions of employment and give direction.
You tell the cleaner that you will work Wednesdays from 9-1. Y, clean bedrooms, bathroom, kitchen. On alternate weeks clean inside of refrigerator or oven, etc. You supply the cleaning products you want used.
The plumber responds to your call about the leaking toilet and says I can be there on Tuesday between 11 and 4. he brings his own tools and supplies.
