Pros
Good way to build experience if you're pursuing a teaching career. Great way to make yourself a familiar face within a district if you commit yourself to work at the same district everyday. You might even get offered a position at a school if you have the certifications. It's also a great learning experience. Working in different schools and grades will help you decide what kind of teacher you wish to be. If you are a college student, it's a good job because you make your own schedule and the hours are short. The most rewarding outcome of being a source4teachers employee for me was the fact that I got to work at my childhood schools where I grew up. I got to work with my old teachers and got to receive great career advice from them. I also became a familiar face. The children recognized me everywhere I went; at the mall, the supermarket, etc, children walk up to me to say hello. I eventually got a permanent position through MissionOne as an autistic paraprofessional and I love the job so much. I look forward to working everyday.
Cons
Source4teachers and MissionOne employees have a bad reputation. You will get discriminated by the school staff... As a source4teachers substitute, everytime I walked into a school I felt like I was not trusted. I had staff check up on me often. I felt like my every move was observed and judged... I also worked a permanent position for missionone as a paraprofessional for autistic children. There was another para working with me, except she was a district employee. Me, as a MissionOne employee got treated differently. The teacher and the other para would whisper things about the job to each other because I guess they thought a MissionOne employee isn't worthy of knowing the insiders. I also am not as trusted as the district employee. One referred to us as "you MissionOne folks." On a side note, the medical benefits are not beneficial in any way. You don't have sick days, you don't have paid vacation. Zero benefits.
