You are essentially trading stability and safety for money in most cases.

I know this is reddit and corporations only care about themselves blah blah blah, but you always try the hardest to save the folks who are ingrained in the system, have long standing relationships with other people, know all of the crazy nuances and culture, have that one piece of useful knowledge that saves the day every other year or so, etc when cuts come around.

in MOST fields, 3 years really isn't enough to get yourself in that spot.

Reddit is a bit IT\IS heavy if i had to guess when it comes to careers, and rules are somewhat different there. You don't want to get caught in a place where technology and your skills stagnate. Some little project you worked on at your current job may now give you the push to go for higher pay at someplace else where that is the MAIN job, etc.

As someone who was a hiring manager, you liked seeing nice stretches at a previous job, vs the 2-3 year flips. Ideally you saw a little bit of both...."I was with the company 8 years....everything was great, but i didn't see a direction for me for some time moving forward..."

Hiring someone who you knew would start shopping around in 2 years was always a strike against you, because if you aren't a mom and pop, hiring\firing someone is a giant pain in the ass, expensive, and a time suck, and if you get it wrong, you can fuck up existing stuff that works.
