"Coworker Bonus Program
Employees can reward each other with a $50 coworker bonus. That’s right! Zapponians can show their fellow coworkers how much they appreciate them with moola. So, you might be wondering, how does this work? Bonuses are obviously given for work-related reasons. Each Zapponian can give one bonus per calendar month, but they can receive more than one as long as they are from different employees.
Managers, supervisors, and team leads are not eligible to neither receive bonuses from their direct reports nor issue one to them. This bonus system isn’t abused since it is monitored and subject to withholding at the time of payment.
Having employees give bonuses allows both the giver and the receiver to spread happiness. "
