The minimum payment for work that the GrafterNow Platform supports is four hours (half a day). The system cannot handle payments for time less than this.
If the Grafter decides to leave the job before 4 hours have passed, they will not be entitled to be paid for the time, as they failed to complete the minimum time commitment.
Any payment for time worked of less than four hours would be for the minimum four hour payment and would only be paid at the clients sole discretion.
