My only contribution in 25+ years of employment is this:
We were running a product study for one of the drug manufacturers, using non-human primates. The monkeys had to be given a tablet twice/day, every day. During the weekend, the dosing was shunted off to all the lab staff, so that all of us had to come into work twice/day each weekend to dose about once/month. Kind of a pain in the neck, but the nature of the beast.
Well, the study required that we keep track of the drug, so each week the study coordinator would count out the number of days x 2 x #animals and add 10% for breakage/loss. The people dosing weekends had their own stash of drugs for that weekend. We were paid a LOT of money (I'm talking a couple million $$) by the company to run this study. I'm at a university and grant funding was really tight at the time, so this study kept us afloat until we could bulk up our grants.
There was one guy who was hired that his total responsibility was the animals. His responsibility was dosing during the week, sedating the animals for testing, giving treats and taking care of the animals beyond what the staff vet did.
About halfway through the study, the study coordinator noticed that a lot of pills were remaining in the container at the end of the week, despite the fact that the guy who dosed logged in the dosing. So each night for 3 weeks, the study coordinator came into the lab and counted the pills, noting when there was a discrepancy between the amount of pills there should have been vs the # that should have been used to dose that day.
All of a sudden the study was cut short, all samples thrown out and things came to a screeching halt. Turns out the animal person was cheating on the logs, saying he had dosed the animals when he hadn't. The idiot didn't even have the intelligence to throw out the pills he *should* have dosed with, he just left them in the container. He is the ONLY person who I have ever worked with who was immediately fired on the spot (which isn't easy to do in this system). Fortunately the company that we were working with gave us another opportunity to complete the study, but the animals had to rest for a couple months before we could start the study all over again, which meant that things were financially VERY tight for about 6 months.
