Instawork does not require a minimum number of hours for each shift. We do recommend booking shifts that are scheduled for at least 4 hours.
However, longer shifts are more likely to get booked by Instawork Professionals right away, especially when they're located in areas without easy access to public transportation.
You can also send a Professional home early if the Professional has completed all tasks. The time the Professional clocks out will be reflected in your billing. You can also adjust your Professional's clock-out time in the dashboard.
Professionals make sacrifices to work your shifts. To compensate the Pro for their time and effort, there's a minimum 4-hour charge for a shift. If the original shift block is fewer than 4 hours long, they will be paid the entire shift length.
