I am in the field of higher education in technical fields. My response is as follows.
1. WFH is a compulsion, it is not an option. It has been necessitated by the circumstances and unless you are able to adapt, it will become difficult to survive. In my establishment of nearly 100 employees all are working from home. (100%)
2. Apart from cost, space utilisation, family time, work-life balance, quality of work life, the advantage I am able to see is the realisation of importance of human relationships, particularly in families. When one is forced to spend more than a month confined to the four corners of limited space, the realisation of family relation, be it between spouses, between parents & children, between siblings or with the grand parents has definitely led to more understanding and appreciation of each other.
As regards disadvantages, there is a need to relate to a wider world that is being missed, a lot of misapprehension as fake news grips the lives. There is a lurking fear that something worse is going to happen.
3. It is only the compu-savy generation that has been able to adapt themselves to the needs of the time. Others have not been able to cope up with the sudden unexpected crisis
4. In these times, managements have to think out of the box to devise new ways and means to keep the productivity up. There are no standard measures or text book solutions to this crisis. All industries need to invent themselves
