There was work done by Professor Linda Duxbury a few years ago. She's at Carleton University. She found—and this is a huge contributor I think, particularly in the police community—that most police officers were working an excessive number of hours on a weekly basis. Let's say roughly that we work about a 40-hour work week, as everybody else does. But she found through her research, which is a national research project, that police officers were regularly putting in between 10 and 20 additional hours on top of the 40 that they normally work. So when you talk about burnout, there's not a police agency or a police officer across this country who won't tell you that on a weekly basis they're having to put in additional time.
Sometimes that's because they're appearing in court to help prosecute the cases in which they've arrested people, so victims can be supported and the accused can be convicted of the serious crimes they were committing. There are special events. There are always additional demands on police officers, in addition to the regular hours of work they typically do.
That's just one example that leads to this burnout, this constant demand.
