Not a Staffing Agency. StaffMate Online is the first and only staff scheduling program created specifically for the special events industry. It has the power and flexibility to transform the way you schedule your own on-call staff. For decades, the drill for staffing coordinators has been the same: call your employees, muddle through busy signals, voicemail and call-backs and field employee 'clarification calls' about what to wear, where to meet and how to get there.
