Interesting!
Several years ago, while still active, had a GC that decided to require tests of all subs. At that time false positives were not a rare exception. I, and my attorney, drafted an acceptance form for the GC to sign along with our people. In it the GC accepted full responsibility for the accuracy of the tests and any positive had to be verified by two additional labs. If the original was proven wrong, the GC was liable for $50,000 per false reading. The GC decided that subs would not be required to submit to tests.
BTW, my company had testing for all employees including office personnel.
