Nikhyl Singhal makes an important point below that no company can actually ever reward their top employees enough because they will always contribute disproportionately more than what they get compensated (maybe unless you are a founder where the success of the company flows back to you).
Recognizing one’s own value and managing one’s own boundaries then become valuable skills because the company will never help you with this since it’s in their interest to extract that disproportionate value from you (thank you, capitalism!). I burned out at Google before realizing this – I thought my manager would protect me from overwork but instead they kept piling on more until I collapsed. I had to learn to say no to work I didn’t want.
I once heard Silicon Valley described as “harnessing anxiety disorders for productivity” and that rings more true for me over time. Companies will happily use you up and discard you to replace you with the next up and comer. It’s up to each of us to find our own path within that pattern.
