Apple Songbook Products Limited has service agreements with independent contractors to write sheet music for the music books it produces. It provides the contractors with an app that requires the contractors to transpose the music into written form. The app provides a deadline for each song submission, but a contractor can skip a song if they do not think they will meet the deadline. The contractors get paid on a per-song basis. If they do not complete at least 15 songs per month, however, their access to the app is revoked. Apple Songbook Products Limited has a studio with a variety of instruments that the contractors can use to help them transpose the music. It is only open from 9 am to 3:30 pm.

A long-time contractor has recently sued Apple Songbook Products Limited because she does not believe she was given proper notice of termination.

Please explain What are factors that a court may consider in determining whether she is or is not an independent contractor.
