I currently code for a specialty clinic. My problem is I have been offered a on call ED coding job. This job would require me to work some evenings and weekends. These hours will not impact my current employer. I don't know if I should let my current employer know about this position. Our handbook only mention that we should think carefully about doing this. It states that current job performance , attendence, tardiness is no excuse because of this issue. It can not be an excuse to leave work early or to refuse overtime. I know this new position will not impact my current job. Is it unethical for me not to mention it? I do not have any plans on leaving my current job, just need the added income and this would be a great opportunity to continue learning new skills in a different area of coding.
