Hours cut in half

Let me start with this..I love love love my job. I love my co-workers, my bosses and my residents. A few years ago, I was working both PM and NOC shift. The PM shift was hard on me and my family and esp during the school year. So I cut the PM shifts out and that put me at part time. I LOVED my new schedule.....my bank account...not so much. My hubby worked too but at the end of the day...it was a struggle. So I went to my boss and they had no other shifts open...even the PM shifts were full. I started looking for a part time job...and was offered a full time job..16hr shifts...two days a week with e/o weekends or work every weekend with a baylor bonus. . I went back to my current boss to see if they could offer anything similar and they said no. So..I went on call (mostly part time, but I was considered on call) and took the other position...16hrs..every weekend...3p-7am.. At first, I loved it..it was very different and a much bigger facility. Then things started to happen that I was not 100% comfortable with...like me being the only nurse for 112 patients with two TMAs and 5 CNA's during the night shift. It was busy and I handled it...but to me it was a bit much. But I kept on trucking.

About a year later, I was called by my part job DON. She offered me the weekends I have been wanting, and the hours. I told her I needed to think about it and she said she would match my current pay and add $2. After a few days of thinking about it..I went back to my old job...dayshift...7am-11pm every Sat and Sun.. It is a smaller facility..lot less stress...less drama...and overall a better job. I loved going to work and it has been amazing for the past two years. Now I am the only nurse at this facility that has these hours. All the other nurses work 8 hour shifts. I never really paid attention on how they have been making it work this long...but it has. Until June of this year. I was pulled into the HR office and she said that I would need to give up one of my weekends because it was no longer going to work with me working every weekend. I asked why and all she would say was that she cant do it anymore. That's it. We did have some new nurses start but I am not sure if that is why. I basically begged not to change my schedule. It works so well for me to home during the week with my children and I am starting RN classes next week. I told her no.. I needed my schedule as is. I was told to talk to the DON. I went to her and she said that for now..it wasnt working and that we could look at it later. We sat down and did a block schedule and it works...for now..but I lost the bonus pay. I was able to keep my weekends that I do work to 16hrs but yesterday I got a note saying that I would not be doing 16hrs any more and that I need to see her about my new schedule. I have been a nurse for a long time..and this to me is wrong. I went to my DON this morning but she was in conferences all day and said we could talk next week. I feel like I have to fight for my hours. On a side note...I do have a part time job that I could go full time with...I just rather keep my old job..just feels like I am being forced to change my hours w/o a valid reason why.
