We often get asked how to force certain hours to be overtime. In many companies, employees get paid a premium when performing duties after hours or when they're on call. That's easy to do when using activities, but first I want to discuss the difference between time clock software and payroll software.
The purpose of time clock software is to keep track of how many hours an employee has worked and then total those hours in an accurate and easy way for payroll processing. The purpose of payroll software is to assign rates to various types of hours to meet state and federal labor requirements, and employee contracts. For example, Virtual TimeClock allows you to assign overtime rules to employees, and those rules define when the time thresholds are met for premium pay. Because overtime calculations are based on minimum thresholds of hours worked, there's not a way to force hours under the threshold to calculate as overtime. That's where activities come in.
Since every punch time in Virtual TimeClock gets assigned to an activity (even if it's just the default activity of 'In'), it's easy to separate the number of hours that need to get paid at the premium rate, which is the job of your payroll software. Go to the Lists menu and choose Activities. Add a new activity called something like 'On Call' and make it available only when adding manual entries. Now when employee time cards are generated you'll know how much time to pay employees for on call duties at their premium rate.
