Thanks to you all for your input.
FF, yes he would get OSP and he's worked with the society fro 24 years.
O.G, the only crowds he has to deal with are those on the trains ! Only about six customers in branch per day now.
TTT. he is not sick in the temporary sense, just at risk with his underlying illnesses.
TCL @11.48. Problem is that his main concern is the crowded travel, and I'm sure the company wouldn't accept any responsibilty for that !
Thanks again. D
