Not mentioned are drug tests and background/credit checks that resemble security clearance checks.
Unless you are an elected official. A janitor has to pass a drug, alchohol, credit, criminal, and lifestyle, background check these days.
Running for president............Not so much!
We are friends with the HR director at the local public hospital. He says that about one-third of the applicants for all positions (including nurses, technicians, etc.) either fail the drug test or have disqualifying criminal records.
