I will caveat this with that I actively have just over 14 years of workplace experience in my "field of employment", which since I am a /.'er, I guess that lumps me into IT in some what shape or form.
With that, I live in a right-to-work state and spent almost 9 of those years as a government contractor. I endured the typical BS: pay cuts, freezes, lousy raises, a government furlough, health care hikes to make you make less for that year with your raise, benefit slashes with contract renewals going to the next company, shitty co-workers, shitty projects, shitty managers, worker shortage, attrition, ect. I could go on and on. The point I am making is: I was afforded every opportunity, reason to quit and walk the fuck out and there will always will be reason after reason to make you want to quit your job without reason and throw up the double fingers. The grass is never greener anywhere, it's always the same, drab shade it will always ever be, it's just what you make of it.
When I finally decided it was time to go, and move onto another position I was approached with in the private sector, I had plenty of vacation banked to take off a month paid, then put in a hastily typed immediate resignation letter and walked right out the day after coming back in. Did I? I would have loved to like anyone else dreams of doing but I didn't. I worked out my two weeks faithfully, documented things, properly transitioned work off as best as anyone can and took the high road. Why? What reason did I have to burn bridges? None. What if I want to go back? Would it be worth the happy hour story of being the Robin Hood of Everyone-Wants-To-Be to tell that one story where you told your employer to fuck off? Probably not.
People have very little reason to in general to spite their employer back and not put in a courtesy two weeks --- usually the things that burn us and drive us to that point all are business or environmental culture things that are most of the time out of our control and end up in the constant cross fire in. Did your job, as long as you did it, always yield a paycheck and some sort of benefits? Isn't that why you were there to begin with?
I'm not advocating you stay in toxic, cancerous or career suicide workplaces, what I am saying is there is this definite trend in people today, especially the millennial YOLO brats that have an over-inflated ego of worth and dedication. I was raised to do a job, do it well, never half ass and build a brand and name for yourself. Others don't operate that way.
