Yep, suddenly all the projects are back but not the hiring to go with them, and I was already stressed and doing multiple former employees' jobs and underpaid in a hot developer market, so...why should I stick around any longer?

Currently interviewing with several recruiters. One will definitely give me a higher salary than I can expect from my company, if they ever decided to give raises again (this year's annual review came and went and other than having me fill out a self-eval four months ago and hearing nothing since).

I even kept quiet in meetings for upcoming projects recently where I was told by other people in the company "You better not leave, we need you for this!" Not my problem they don't have "Hit by a Bus" redundancy in place.
