Pros

Lots of jobs available. Once I began working in certain schools and built relationships, I spent the majority of time in those locations. Flexible.

Cons

Not easy to get in contact with the recruiters. Application process was muddy and unclear. Took me longer to submit all the paperwork and receive answers from the company than it did to start working.

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.
