I think it’s a mistake to implicitly trust that your colleagues and employers are working hard on your behalf. Most people are selfish, and when pushed, will do stupid things to survive.
That being said, life is all about trust. You can’t walk around in a paranoid state. It’s not healthy. At some point, you have to take a leap of faith and hope that you won’t get burned.
Most of us get burned from time-to-time. That’s life. We learn from it.
I can’t believe that I’m saying this, but I fall into the Reagan camp when it comes to colleagues and employers. My favorite phrase is trust but verify.
I also like, “Fool me once, shame on you…”
(That one comes from my gramma.)
