Ummm, excuse me, stupid excuse for a mayor, but just exactly how much is it going to cost you to continuously test your employees to find out if they are smoking during their private hours; ie. not on the clock?
How much is it going to cost taxpayers for you to hire people to spy on your employees during their weekends?
How will you justify your expanded costs in this arena?
As an employer you only have the right to dictate what happens on the job, not off the job. You should go back to school and try a little more fundamental education, not socialistic domination.
