Also, that call I went into the office for this afternoon: sat around for 2 hours, waiting for the call to happen, being half-productive (such is the cost of being in an open-plan office) and then buggered off for a long walk. There's nothing like feeling that your time isn't being respected.
I report directly to the international CEO of this (admittedly small) company, who is based in the UK, so I didn't really interpret my being asked to a conference to speak to UK senior management (which would have involved at least one of the board of directors) as a "let's give the HK office some cheer during virus season".
