Applications for employees working remotely ui/ux, web-design

Employee problems remotely! It is difficult to establish communication, it is not clear who can be contacted with questions about projects, which colleague can be asked to help, or from whom the question came. It is difficult to track the workload of colleagues, for example, who is free now and will be able to fulfill the request, or who is better not to be disturbed, for example, a colleague on vacation.It is difficult for beginners to understand who is who. Employees who work remotely can forget about phone calls, lunch or the end of the working day. Not enough positive feedback.
