Spoke with a colleague recently, who told he had not gotten a raise in 4 years.
He is one of the most productive person I know. The situation he is in is simply disgusting (no raise for 4 years and he is a single dad).
He told me he did not want to make a "fuss" and that he was happy to have a job. My response was something close to: "F* THIS SH* YOU NEED THE MONEY!".
I told him the goal of our company is to make him work as long as possible, for as little money as possible.
