Surely its inevitable that someone within ATC catches it somewhere! Suppose different employers will have different plans in place. At the rate things are going there won't be that many flights disrupted if there's no controllers anyway! We are on permanent disinfection mode in my unit, hand washing and sanitising everything including phones and touch panels. Are we just kidding ourselves, who knows?
The real question and debate amongst my colleagues is what state is ATC going to be in when this is all over. Airports are going to want to cut costs drastically over the next while, contracts are going to come under immense pressure - both NATS and private ANSPs. Reduce ATC staff to the bone now with redundancies and it'll be difficult to get back up and running again if traffic levels recover, maybe traffic levels will take so long to recover it won't matter. Lots of questions but no-one with answers at this stage, not a good time to be in the business.
