Rhino Network Solutions

San Carlos, California, United States

Many companies lack a communal system for the scheduling and attendance of their staff. This leads to miscommunication, too many workers being away at the same time, as well as employees' absences not being monitored properly or consistently. Currently, the most common way to manage this, is to have multiple calendars which are manually administered. Even with this in place, mistakes happen that cost your company in real terms. At On-Semble, we help companies work more efficiently, through a unique, company-wide scheduling application that increases productivity and profit. We also reduce the time and costs of administrative overheads through automation of office-wide schedules and absence entitlements.
