Working in a Mosaica school was a wonderful experience with great co-workers and managers. Very much enjoyed this part of the job.
Working for the top leaders was constantly a balancing act. Their entrepreneurial focus did not translate into student performance at the building level due to a lack of competent people who knew anything about educating children. People were let go with no notice and no real reason, other than the whim of one of the founders. Don't say the wrong thing to the wrong person or you are doomed with no chance of recovering.
There is no loyalty to employees so don't stick around too long.
Great people at the individual school level.
Little job security, lack of systems in the company
