Nice piece, and totally true. There’s an even bigger danger for people who work remotely or are field based – people will assume just because you aren’t at the office that you’re sitting at home watching netflix. I’ve known people who outworked everyone based in the office, but due to the lack of face time were undermined while they weren’t there.
Bottom line, people aren’t just subjective, they can be total dicks. Protect yourself and do things that are obviously high value and high visibility, even if they aren’t your job.
