Remote working can be very effective, but only if high levels of communication are maintained. Being able to see people's reactions and being able to get to know them is far easier when the camera is on.

The importance of understanding how people work (and what mood they are in that day) can not be underestimated if you want a team to be productive.

Some of my team leave an open video link on between each other as they do their work so they can grab a coffee together or chat about their plans for the weekend.
