I'm the most productive engineer on both of my teams and have been for the 4 years I've been working at both companies. I don't tell them. Nor do I tell them about my sexual proclivities, my rental income, my residuals on several albums I produced nor my stock, crypto and portfolio income. I manage all of that a little bit of "company time", whatever that means.
