Hello, I am working with a small company who help other big companies to establish their ETP plants, currently we have allocated some of our operators on site for smooth running of ETP Plants, and hence we cannot record their attendance through system. also there would be no one to supervise at each and every plant, so very difficult to track their location, their login logout time. Even I told them to give missed call when they reached in company as well as they leave. but they failed to do it. and day by day I found it difficult to manage. Please help.
