Please l need help answering this question

Rebecca has been a coder at Memorial Hospital since 1982. She started as an outpatient coder and about 15 years ago earned her CCS credential and moved to an inpatient coder position. The hospital offered ICD-10-CM/PCS courses for the coding staff - both online and face-to-face for the year prior to the conversion from ICD-9 to ICD-10. Thetraining was offered after the workday, and all employees were compensated for the time, and the hospital paid for the training. Rebecca started the training, but she did not do well, and she did not attend all sessions. During the training period she made it very clear that she didn't want to learn ICD-10, because she felt "it's never coming anyway." Also, because the coders are unionized, she figured nothing of a disciplinary nature could happen to her. She did take the ICD-10 proficiency exam through AAPC, which she passed, but only by one point. Now that ICD-10 has been in use for two years, Rebecca's productivity is below the acceptable level, and her accuracy rate is at 80%, well below the acceptable level of 95%. She feels it is the supervisor's fault, that she was not trained properly, and feels that nothing can be done to her since she is part of the union. She is very vocal about her feelings, and she is difficult to work with because of sarcastic comments like - "let them try to do anything to me, I'll sue this place."
