In my experience attitude is everything. We measure their KPI's. If it starts declining we have a conversation as what might be going on. If they do not care it can be spotted and we let them go. I am also for working with someone if their speed is not up yet but you can see how much they want it. Attitude trumps over everything. Dishonesty will also get them fired.
I started implementing KPI readouts during my difficult 1-1s with technicians who aren't reaching benchmark expectations. It's much easier to say "you're doing X jobs per hour, and I need you at Y. I literally can't afford you if you stay at X" lol
But I already gave someone two chances now showing their performance is meeting our expectations. I gave them a deadline to improve by so we'll see what happens.
