Why do you think this is the case? Some people can never get enough, i know some people who complain so much that you'd think they were living in the streets but their household income exceeds 500k, it is just a mentality thing.
Totally agree unless they want to complain about it to me. If a peer or employee tried to sell me a sob story about 500k not being enough I would tell them to hit the road
again, you have no idea what’s going on with their life or finances. people find themselves in situations all the time they think would never happen. hope you never end up there.
As long as you can fire them and find a replacement for the same price, why would you ever increase pay? Especially for a worker that is underperforming?
