My previous two work places have had power during load shedding so this is only the case when your employer also can't afford a load shedding solution.Load shedding is no issue for remote work. Why would it be? There is no difference between remote and in-office for load shedding. At home I have a working big screen while in-office I have to struggle on a small laptop screen.
I have a 1440p monitor at home so it's a big difference on that front too but any decent development company will give you at least a 1080p monitors (if not 2). Other industries seem to be particularly bad at realising screen real estate boosts productivity.
