AMs
Good - convenient for those with families, relatively normal working hours (often easy to get rest), normal pace of work, jobs not often seriously affected by GOs (except on weekends), AM tour has the most overtime (penalty jobs)
Bad - on time performance is important and lateness is questioned, large crowds of people, if you drive to work this is the hardest tour to commute in and out on, early AM jobs are very difficult to commute using the system itself to get to as service is minimal in the wee hours, most non-RTO supervision is out during AMs (IE the people that will take you out of service if they observe anything even if minor...remember most RTO supervision is there to help you not write you up).
@SubwayGuy who is NON RTO supervision?? Just curious on this.
