Read full description

The Workforce OS mobile application provides interpreters with the information needed to be sure they do not miss an appointment and that their time sheets are submitted quickly, accurately and already approved by the client. Not only do the interpreters have all of the relevant information about the appointment at their fingertips, they even have a map for the location. Once on site, the interpreters can track the actual interpretation times using a timer to calculate and record the times. Mileage, parking and other expenses can be recorded as well. When everything is finished, the client can review and sign the screen with a stylus or their finger. The information is then submitted and stored in the Workforce OS database with a date/time stamp of the submission. If the interpreter does not have internet service, the information is submitted once the interpreter has internet service and refreshes the app. The Workforce OS mobile application was designed to be an extension of the Interpreter Portal for those companies who already use Workforce OS. Those interpreters who do not use smart mobile devices can still use the portal.
