We are no different than anyone else except for the type of decisions we have to make. Because we face the same trials and tribulations, we are subject to the same perils and pitfalls that help create collateral damage. The only hope we have is to be very aware of warning signs and emerging patterns so we can mitigate issues early.
One of the keys is being keenly aware of changes in behavior and the accompanying work product. Most problems don't surface overnight but will be noticeable over an extended period of time, creating a pattern. If you find that an officer has gone from a go-getter to a no-getter, it is time to find out why.
In general, warning signs include employees who turn down responsibility or show a lack of accountability for their work. Look at officers who suddenly show a pattern of being late or start having frequent absences. If they are taking extended breaks, lunches, or put blinders on toward the end of their shifts, they are also worth looking into. The most obvious signs are the ones that display a sudden bad attitude. These officers can't see anything good in the office. Hand them a raise, new car, and choice of assignment, and they will still find something to complain about.
Other signs to look for include yelling, using harsh language, and reverting to bullying. Officers who display these behaviors are the people who always seem to have something eating away at them and never stop being angry. If your subordinate starts to isolate himself from others, expresses feelings that life is meaningless, neglects appearance and hygiene, or talks about getting his affairs in order, it's probably a sign of depression or suicidal thoughts.
If she has prolonged or frequent disappearances, missed deadlines, erratic behavior, or a sudden increase in job-related injuries, these signs may signal substance abuse. Working late into the night without cause, shaving or brushing teeth in the office restroom, falling asleep at their desk, or sudden disengagement from coworkers point to personal issues at home.
