Snipped for brevity: presumably management stayed at home in accordance with their organisation's risk-averse guidance (i.e. stay at home unless you cannot work from home).However she is a Nurse first and foremost so went into wards that were short staffed to help out.
ALL THE MANAGEMENT STAYED AT HOME!
Your missus, in her important role as a nurse, went out and used her skills.
There's no "them and us" scandal in that scenario, just that she had frontline skills therefore she went onto the wards, the pen-pushers had no need to.
