This December I got a promotion and a 7% raise!(Where I live in the southwest US, this is less then the inflation).
Couple of recruiters reached out and I said I am interested and now I am fixed to start a new job that will be a 25% jump from the current job(even with the raise calculated).
This will be my 4th job in 5 years and I will be making 3 times of what my first job paid.
Moral of the story, jump the ship the first opportunity you get. Being loyal to an employer just hurts you and no one else.
