How have you guys dealt with C? It’s definitely something I have felt and am currently pretty keen on getting back to the office even though it probably isn’t the best thing long or short term.
I don't have a general solution. We warn all new hires about this problem when they start. Just knowing you will go through this phase is often useful in catching the problem early. We rely on the support structure of everyone who has gone through the pain recognizing the symptoms in others early. We try to infuse some change to the working pattern of the person - like increase the 1:1 communication or have them help someone else or make them present something at a virtual brownbag or teach something to the rest of the group. These tasks help to a certain extent because new people seem to feel good when they contribute to a group. But I don't think there is any easy way other than just accepting this is going to happen and that you need to experiment your way through this problem.
