Would like feedback on dialysis nurse job offer

[Marshall1]

I've been offered a position for a chronic dialysis clinic nurse. I do not have dialysis experience. The company is going to provide the training/orientation both online and in person. The pay and benefits are reasonable given my lack of dialysis experience.

The hours/schedule differs in the offer letter than what was discussed in the interview. In the interview I was told it was 3 days a week, 10 hr shifts starting at "around 7 a.m & done by 5 unless  some issue that comes up"  The offer letter states "3 possibly 4 days a week depending on patient and facility needs, 12 hr shifts with times to vary depending on facility needs".

One of the main reasons I applied for the position was because it was not 12 hr shifts & was 3 days a week. I understand things happen & there can/will be days that are longer than others or an extra day may be needed at times but I guess what I am asking is   12+ hr days the norm for chronic dialysis clinics? This clinic runs two schedules morning & mid - there is no evening or noctural shift.

Any feedback I would appreciate.

No one has answered but after rereading the offer letter I am going to deline the position. It sounds like it would easily be 12+ shifts 3 days a week with a 4th most weeks. There is also a probably to travel to a sister clinic over an hour a way. I don't mind working but I do not want what should be my days off spent working over or working another clinic on a consistent basis. I admire nurses who are willing to deep dive into this kind of chaos but where I am in life and my career right now, its just not a good decision for me. Glad I took some time to reread the offer letter & compare it to the interview conversation. Some was similar, much was different but it all meant I was the one giving in/giving up more. Can't to it this time. I'll stay at my low stress boring 5 day a week job because at least there is flexibility.
