Employers I know are fed up. They cannot get their staff to come into work.

I exaggerate. One I met last week pronounced himself happy with his lot: the bulk of his workers were at their desks. His claim was borne out during a visit to his central London premises – they were positively buzzing, with plenty of people in evidence. His were unlike some offices I’ve been to recently – and others I’ve passed and glanced through their windows – that have a forlorn, desolate, scarcely there, feel about them.
