One way to ensure employees are rostered on to meet their contracted working hours is to enter Maximum and Minimum Weekly hours in the employee profile. When these hours have been entered if an employee does not meet one of the conditions i.e. not enough hours rostered on this week - a warning message will appear above their name.
To enter maximum and minimum hours for an employee:
Go to the employee profile > Open the 'Pay & Cost Options' panel > 'General tab' > enter the 'min weekly hours' and 'max weekly hours'.
