If you only pick out half of the sentence then you are correct. However, if you don't ignore the part about waiting in line...It says right there in bold 10-20 minutes PER WORKER.
PER WORKER
PER WORKER
PER WORKER /= IN TOTAL
By your logic at 10-20 minutes per person per search then they would be looking at 16-30 man HOURS to check those 100 employees.
BTW: The all caps and repetition doesn't help your case in the least but go ahead and keep gnashing at a simple internet post.
