In remote work environments - where you are generally not regularly exposed to non-verbal communication signals from team members - it can be easy to miss the first signs of conflict.
One of the easiest ways to increase your awareness of the frustrations of your remote team members is to develop an understanding of their basic communication habits. Irony or sarcasm may not be of concern if this is their standard way of operating. But increased negativity from a generally positive worker, on the other hand, could be a concern.
Don’t let tacit problems and bad situations persist. If you see these types of changes or other signs of potential conflict, proactively resolve them.
