Helpful if you cannot find any other job--although, welfare might be a favorable option.
Cons
No union. When you sign a contract with OHVA they can terminate you for wearing the wrong colored socks! Colleagues disappear frequently with no explanation. Employees have no rights or protection. This company exists for one reason only; to make a profit. A former CEO was pulling in 5 million a year while the rank and file make diddly compared to real schools. Teachers are forced to pass students who have not mastered the requisite skills for their particular grade levels.
