A crappy job is why I retired when I did! I had been doing something I looked forward to every day but that division was eliminated and I was transferred to a job I didn't like. I had planned on retiring in three years but I talked it over with my wife and we both agreed that the extra pension dollars wouldn't be worth three years of stress and being an a$$ to her. If you enjoy the new job... fantastic, a job you love really isn't work. But at our stage in life don't do crappy work if you don't need too; retirement is great.
I wish you the best.
