What I'm learning from these threads is that those economically better off are able to better protect themselves. Home working favours those higher up the pay grades.
Don't believe everything you read on any threads as being wholly accurate or complete. It gives a partial picture only, based on who's posting.
I can't speak for every branch of CS, but mine is one of the largest departments in Government, It is simply not true that only higher grades get to work from home. Anyone, from E grades (administrators) upwards have the option to have a laptop and many EAs habitually wfh already, even before Covid19.
I'm a higher grade and I often go into the office more than some of the lower grades! My choice - often because of management responsibilities or f2f meetings, but CS tries to treat employees equally.
Gone are the days when admins had to be in the office because they had fixed desktop PCs, they can have a laptop. With Skype on laptops, people can continue with meetings as if they were in the office, and there is meeting etiquette to ensure people dialling in on Skype are not excluded from discussion.
If anyone has any medical risk eg respiratory or autoimmune compromise, or a Reasonable Adjustment, they can elect to wfh with immediate effect. It's based on trust, and 99.99% of CS people are totally trustworthy and work effectively from home. Remote working guidelines have been in place for 2+ years, and recently updated for Covid19 circumstances. There is a Pandemic (generic) business continuity plan in place, and we get daily updates from Government on any changes in response to the UK CV situation.
