To address "abuse by parents", I am not referring to physical violence. Abuse by parents in the sense that a group of parents can conspire to "punish" a teacher they perceive as being unfair to their child by not bidding on that teacher's class, potentially resulting in the teacher being fired.
The racial barrier doesn't mean that it has to be inherently racist. It can simply mean that, for example, white parents avoiding African-American teachers. Or vice-versa. A bidding system such as this could potentially result in an unintended segregation within the school.
In many school systems, there is already a "bidding" process among schools that put the good teachers at the good schools and the bad teachers at the bad schools. It is called school choice and allows parents to choose which school their child goes to.
