In the private sector we did not have security clearances for my type of position, but you had to be "bonded" .... and those underwriters did NOT play with literally millions at stake.
On a similar PARFy topic, when I was in R&D at IBM in their very secure & protected sites and labs.... being lax with classified/secret/top secret documents would get you fired. You didn't even leave them out on your office desk to go take a leak
