I don't understand this argument. My interpretation of "essential" with it comes it ICs is someone with a vast amount of domain knowledge which is critical for the continued operation of the company. I've worked at many places where essential workers were in other countries, and I didn't know if they worked in an office, from home, or from a ski resort. But it didn't matter because they had the information I needed.
