As you may predict, there was a reason for the question.
Prior to probably 2020, it was a flat "no" with silly reasoning. The last person that got shot down was a K9 handler that wanted to go a K9-related class that we could not afford to send him to. He was going to pay all the costs and just wanted the time to be treated as regular pay (no overtime or anything...just count it as a duty day). He was denied because 1) the other K9 handler wasn't going to get to go and 2) if they approved this, people would want work time for all sorts of things. Both stupid arguments but there was no negotiating on it. He ended up just not going to the class out of spite.
In 2020, following a change in admin, I got approval to go to a couple classes. The PD gave me regular duty pay, no overtime, no ammo, no gas, per diem, etc. The classes (Sage Dynamics RDS Instructor and Centrifuge VCQB Instructor) were massively helpful to us implementing our RDS and vehicle programs. Following those classes, we generally were allowing people to go to stuff. I believe since then we've send people to Reston, Pressburg, Modern Samurai Project, Symtac, Centrifuge and probably others, plus some of the Street Cop Training and other classes. This culminated in me hosting No Fail Pistol and the PD authorizing backfill overtime for anybody that wanted to attend. We sent 11 or 12 people, all on their own dime, which I thought was pretty awesome since most of those people had never done an outside class and probably would not have done one if they had the additional burden of travel costs.
Recently, I signed up for a class with Donovan Moore (Point 1 Tactics), which happened to be on my day off, and have been told that we are now only willing to cover people's time on a work day. They also did not like that I did not ask before registering, but I've been very clear with everything I have attended that I am going to attend either way and that often classes fill faster than our agency can process a request (this class filled in hours). The whole thing seems silly to me. I know they don't know me anything and that any allowance for something like this is a perk, but it flies in the face of several years of normal practice and is overall kind of a kick in the dick. I think in the long run it will discourage people from seeking outside opportunities.
So my thread is half data collection and half pity party.
