Hiring your relatives can also be inappropriate if they do not go through the vetting process.
We are in full agreement on this.
FWIW, I’ve never seen it where I worked, nor where my DH works, etc., but am not familiar with the San Diego Sheriff’s Dept. I have never seen a situation where a family member was hired without having to go through the very same screening processes as everybody else. Again, not saying there aren’t some cases in various departments, just that I haven’t personally seen it nor heard of any stories from the many people I know in public service. Every single person I know who works/has worked in public service got their jobs in the standard way — by passing a number of tests and having the experience and educational qualifications required for the job.
