Mr. Marsden gets Lyddie fired by saying that she has a problem with moral turpitude. This basically means that she is immoral, but since Lyddie does not know what the word means she cannot defend herself.

Since she is not granted a certificate of honorable discharge, she cannot get another job at a mill.
