Anything over five hours is a full day, anything under is paid per hour (I made it so that if they're paying per hour I get VERY close to the same rate as if they were full time). My full time rate is $43 a day. If they are there for 4 hours, it's $40. Part time is a minimum of three hours a day and three days a week - paid per hour. Anything over five hours is considered full time and they owe $43 a day
