Hi. office closings along the circumstances you describe are similar and can be compared to a situation where there's some natural disaster, or extreme circumstances that force an employer to shut down for a few hours (or sometimes even a few days, or more). The fact that an organization was impacted by the set of circumstances in only one office/location, is not relevant. The treatment of employees' wages in this type of scenario depends on the exempt/non-exempt status of the workers affected by the events. If the employee is exempt, and worked any portion of the work week, he/she should be paid their full salary, regardless of shut down (this is also the case if an office closes for several hours due to a snow storm, for example). However, in cases where an employee is non-exempt, then the employer does not have to pay the affected employee for the time the office is not operational (bearing in mind that if an employer takes deductions from a non-exempt salaried employee - this might impact the manner in which overtime is later calculated)
