Every government worker should be mandatorily drug tested. They are all parts of running our country and our country deserves nothing less then sober minded people doing a good day’s work every minute of their time on the clock.
What they do off the clock is their choice, but they need to test sober and fully capable to perform their job in full while on the clock.
I was in favor of drug testing when I worked for the government. I figured it would have gotten me a few promotions and would have obviated the need for RIFs.
