If he signed on EBC in working at-work condition, it is up to him, not EBC. I’ll bet you he certainly didn’t tell EBC about all his medical conditions, anxieties, congenital heart defects, etc. I’m getting the sense here that he wouldn’t be ‘productive at home’ anyway, especially he’s involved in ‘shouting matches,’ etc.
To him, EBC’s temporary accommodation because of Covid and the medical leave alternatives he exercised, he thinks continuation is a RIGHT now. This country is full of people looking for early-outs, particularly ones that no longer want to work and are too young to retire on SS. His lawsuit for pay, etc. and pain and suffering are his way out.
You may be right. That information can only be inferred.
