I get to choose where I live in relation to where I work. I also don't have to go home after work. That is my time to use as I wish. Going through a pat down is not my time. I must wait on my employer. It is also unilaterally redefinable. If $employer comes up with a new screen that saves them shrinkage, why should labor be expected to give up even more unpaid time for the privilege of submitting to it?
