The "official" word on my employer's "operational response" is that we work in an industry that must going, keep servicing the public and it's clients. We must remain "fully operational".
Rather than any overarching guidance each area leader has developed a plan and will communicate said plan for their area of responsibility which will vary based on the specific requirements.
