      Flexible job but pay and hours vary greatly

      Substitute teacher
      Recommend
      CEO approval
      Business Outlook

      Pros

      Super flexible and easy-going job if you stay at the same place consistently

      Cons

      The pay is entirely dependent on the district so it may be subpar and the hours will be inconsistent just based on the nature of the job

      The "Sub"stitution for a Real Career

      Substitute teacher
      Recommend
      CEO approval
      Business Outlook

      Pros

      The corporate support and recruitment team are excellent; they are professional and highly responsive. The onboarding and training process was comprehensive and genuinely prepared me for the realities of substitute teaching. The role offers a great deal of flexibility, opportunities to engage with the local population, and a clear pipeline for those seeking long-term subbing positions or a path toward a full-time teaching career. It is an excellent environment for networking within the education sector.

      Cons

      The day-to-day experience is heavily dependent on the specific district and school culture, which can vary significantly. Some districts provide free lunch, others don’t. Unfortunately, there is often a lack of respect at the school level; substitute staff are sometimes treated as expendable rather than as valued members of the team. There is a lack of job security, as pre-booked assignments are frequently canceled on short notice to accommodate other preferred substitutes. Subs have to work 4 days a month and it’s hard to meet when people are constantly being dropped from jobs. Additionally, the compensation is extremely low, and the benefits package is insufficient, making it difficult to rely on this position as a primary source of income.
