Pros
If you are willing to parent and teach children who may not have their basic needs met (food, stability, shelter, clothes, etc), then you've found the right place. The kids may call you everything negative under the sun but will be waiting for you when you come in the next day. Some teachers, assistants, FCEs, and directors are wonderful. If your working with preschool age, you have plenty of vacation time. Plenty of positions available.
Cons
You must follow the curriculum boundaries set for you, and expect to receive little to no money for curriculum supporting material. Feedback is not received kindly. Sometimes you receive no response from higher ups after multiple requests, yet you will be disciplined for making a decision at all. Your vacation time is only when they allow it (which isn't bad if you can make sure life doesn't happen outside of that window). Higher ups are never content with your work even though they made the blueprint for you to follow. Literally. Don't get me started on being disorganized. If any teacher was even a tiny bit as disorganized as that team of people, we would not have a job. If you do not like to or are not accustom to large quantities of paperwork being completed daily as a teacher or employee, think twice before applying. Turnover is ridiculous on all levels, therefore, quality of work of those hired is questionable due to the need to meet classroom ratio requirements.
