Some people may be thinking of what’s called the “benefits cliff”. At certain points you lose the ability to take certain tax credits or deductions. Theoretically this could result in a higher net out of pocket for you, but in the grand scheme it’s really minor, so always take the raise.
We recently got moved under someone who leads call center operations and they’re wanting to apply similar metrics to the devs to “ensure they’re being productive the entire time”. I told them that there’s lots of work they do outside the normal 9-5 and that you can’t just measure what someone does by lines of code created else you’ll end up with a 30 line if statement instead of a for each letter loop, but they don’t seem to care. If things get implemented I’m just waiting for the shit show it’ll cause.
Could always make it a Lifeinvader moment.
