Tuition Reimbursement for RN-to-BSN or BSN-to-MSN?

I have heard that many health care employers will pay for an RN to earn his or her BSN, MSN, or NP in exchange for an extended work commitment to the employer agency, but I have not been able to substantiate this with online research. Might anyone have any insight into this (particularly in the middle Tennessee area)?

Thank you in advance for your input!
HCA is based in TN, and they offer tuition reimbursement to FT and PT employees.
