Congratulations Theo for speaking up.
In Korea, coming forward as Theo and I did is risky business, because defamation laws in Korea are strictly enforced. I used them myself at one point to get bullies off my back. Unfortunately, in Ulsan, some powerful people, through abuse of power, make a warped use of defamation laws to silence victims and witnesses of the irresponsible and cruel behavior of some hagwon owners.

I too am in my mid-fifties and I know another woman in her fifties who was fired for breaking a leg. She was in the hospital over the Chuseok holiday, so she didn't miss any school time. However, when she appeared at the hagwon in her cast after the holiday, her services were abruptly terminated. It's a shame, she was experienced, she loved children and she was marvelous with them.

Duane:
If you really want to take a chance on Korea and you dont mind working in the morning, you could try E P I K (English Program in Korea). They staff in Public Schools.
If you have a Masters Degree, you could apply with Colleges and Universities.
In those areas, age is not usually an issue.
