Answer 2

There is no "normal" term for one particular job. It all depends on the nature of the assignment. I mean, you can get contracted to work for a band on tour, which could go for the length of that particular tour, or even for multiple. Like I said, it all depends on the terms of the contract.

For as long as they want too, providing they are getting paid.
