How do you compel your staff to come to work on time?!
This is a real problem. I recently had to meet with my evening staff about this issue. I explained to them that they were hired for the 3 p.m. to 11 p.m. shift and that they were expected to report to work on time and be “duty ready.”
I further explained that by them being late to work, they had to rush through the narcotic count and their shift report, and that they would then cause the 7 a.m. to 3 p.m. shift to work overtime.
This is not acceptable. No facility can afford constant overtime, especially due to tardiness from the following shift staff members.
I will admit that this is a discussion I have to revisit at least once each quarter. Good luck to you.

I am a new director of nursing in a facility and I am having some trouble getting my nurse managers to understand their 24-hour a day responsibility for their units. Do you have any ideas on how I can get them on board?
Sounds like the previous DON did not hold them accountable. Start by reviewing the company job description for nurse manager so that you are sure that in this facility it is an expectation.
If it is, schedule a meeting with your managers and review their job descriptions with them as the “new” DON. It is always good to start off a new leadership position by making expectations crystal clear. 
Also let them know what kinds of support that they can expect from you. At the end of your meeting, make sure that everything is clear and ask if anyone needs to speak with you individually.
I feel strongly that the nurse manager position is about accountability for his or her respective units. If the person is unwilling to accept this role, then you may have to look for a new manager.
