Communication and collaboration are already complex issues, further complicated by remote working.
Team workers sitting in different time zones and work never happens at the same time. Real-time communication like video conferencing is great but cannot be done the whole day. Email is limited in its collaborative features.
Real-time communication, like a Video chat, works well for casual hangouts, catch-ups, celebrations, urgent situations and one-on-one meetings. Real-time communication is necessary to get things done fast, and for visibility. The lesser, timid employees are at a disadvantage in real-time communication.
Asynchronous communication is inclusive and democratic, as it provides everyone with a chance to communicate in the same way and be heard.
