What is a Position?
A Position is a particular type of job. For example, if you have 12 people who help as cashiers at various times of the day, you would have one position called "Cashier". If you have certain cashier shifts that are special and need to be helped by only some of the cashiers, you could create another Position - for example, "Cashier-Trainee". Each schedule view can be set to show or not show the Position label for each shift.
A Position can be a particular job at a particular location.
Downtown - Cashier
Uptown - Cashier

Once your Positions have been created, you need to set which Positions each Helper can work.
