We had something interesting happen this morning in our center and was hoping to get some input/opinions. The company decided to have its evacuation drill before driver start times; but close enough to start time where the early birds were there and others was just coming in. There was a lot of problems when some drivers did not enter the building and started either heading back to their cars or heading to our meet point without using designated walk paths. The safety people were going nuts demanding they enter the building and then exit again using the correct walk path. I simply told them I was heading to my car and if there was a problem, talk to me on the clock. My question is, I know it is their property but how does an employee handle this? They dont own me til I clock in and I will not acknowledge their commands til I am on the clock.
