She had NO authority to do what she did. She should have just read a different story and avoided the "horrible, offensive" material entirely.
Subs have to try to do what lessons plans say.
Is it horrible to stand up for what you bleive in the face of unpopular opinion?
If you cashed it, then you took money to do something you don't believe in. While it's not technically prostitution it sure as heck would make you some kind of harlot.
Now, if you really have the courage of your convictions return that filthy lucre to those heathens at the school district.
When you do it in front of six year olds, sending them home in tears? Hell yeah it's horrible. She ruined Christmas for every kid in that class who still believed in Santa. Do you think she didn't know what the results of her behavior would be? Please. She's a sadistic bitch, period.
This is a very important point. As a former substitute teacher in Pennsylvania, I know it can be tough to go into a school and pick up lesson plans to teach when you find (a) factual errors and (b) political biases.
I once had to teach about supply/demand/price controls. The original lesson plan said great things about price controls, yet left out the disadvantages. I felt I would be doing them a huge disservce and would be very unfair to them to give them that partial understanding...so I told the principal that I'd like to cover both sides, and he agreed. Often, the adminstration is very busy in the morning, and that's why I went in early to review the lesson and meet the staff. And I think the students probably gained a more thorough understanding of pros and cons of a free market with the role-playing we did (the class had to decide whether to spend the money to drive to sell supplies to the hurricane victims that were price-controlled, and it turns out the poor people in the hurricane area got fewer supplies, etc).
If anyone thinks substitute teaching is lucrative...guess again. Very low pay, no benefits, etc. And not all teachers can think on their feet to create an activity. But at the very least, as this teacher has noted after the fact, there was a far better approach than she used in this case.
