From my experience working with remote workers, problems tend to be bucketed under &quot;loss of context&quot;. The remote worker misses so many ad-hoc (e.g. lunch with a colleague) workplace conversations that they end up knowing less about what is going on. 
Time zone differences further complicate thing (misalignment of working hours).<p>Secondly, and something perhaps tech could solve, is difficulty of working on problems together.  I haven&#x27;t seen a good video conferencing solution that comes close to two people in a room drawing on a whiteboard.
