Kinda got caught in the same situation long ago. When I changed jobs I made it known no weekends (except for unusual situations) and 3 weeks vacation a year and the salary wanted. After the interview I went home thinking no way was I getting that job, and it was so perfect. Got a call back the same day and asked to come back in. Was handed a letter stating I got the job and all the items I wanted. Loved that job, worked hard and was well compensated. Was devastated when they sold out to a hospital corporation. To my surprise, my original letter of employment was honored by the hospital with a few doable changes. Learned, get it in writing.
Sorry you got caught up in this situation.
