The most important employment lesson.
1. HR is not there to protect you. They are there to protect the company.
2. Document EVERYTHING.
3. Food is not a reward for hard work.
4. Do the bare minimum, or you'll get rewarded MORE work.
5. Use them sick/ vacation time/ PTO.
6. Everyone is replaceable.
7. Keep them emails.
8. Your family is more important than any job.
9. Some of your coworkers secretly hate you.
10. Never stay at one job longer than 4 years unless the pay increase is substantial.

I was 100% onboard with 1-9. I don't disagree with 10, but it surprised me as I don't see a real reason for it. I mean, sure, don't be "loyal" to them to the point you're giving stuff away for free, but if the pay and benefits are better where you are that the alternatives at the time, what's the point of switching? Maybe it's more that you always want to be looking for something better so you don't get taken advantage of out of intertia? idk

@Blort @cmconseils
It turns out most companies only say they love loyal employees, but in reality pay new employees better than loyal ones.
But sure, not all companies are like that.
And it also depends on the job market.
@Blort @cmconseils Apart from getting raises it's about maintaining your employability, lest you end up locked in an unbearable situation. Could be a new boss, a reorg, or just the outside world requiring a move. Being prepared is always a good idea.

@Daseinsappeal @Blort @cmconseils IME it’s okay to violate #10 if you’re a very adaptable generalist with transferrable skills or a leading expert in your field.

The dangers are mostly around having to change jobs after 40, because of discrimination. Common traps include becoming overspecialized in role or technologies or becoming middle management, the constant target of layoffs and the scapegoats for poor leadership.
