Mark - we are literally dealing with this issue today with the heavy snow , high winds and low temps in WNY near buffalo and 2 great lakes- Erie and Ontario. Our motto is " we Never close". most of our workforce would be considered essential but like you except for continuous operations like Sheriff, Hwy, Jail, NursingHOme, EMS DMV and DSS we let employees use their discretion and leave credits if they are uncomfortable trying to drive to work. our 500 sq miles provides for some variable conditions within the county and we have 14 facilities including a GA airport to keep operational.The NYS Thruway bisects our County and we have 3 interchanges off the thruway so that engenders more issues with Truck traffic and how to get them safely off the THruway and onto our local reststops till the weather subsides. In the past selective office closings has been more of a pain and problem with unions than adhering to the above Motto. At least it's not a hurricane or tornado zone , both of which I've lived and worked in in my local government career.
