Your options:

1- Remove this employer from your resume'. If asked on an employment ap to explain any gaps in employment, just put down "seeking work". Or you could put down "please ask me" and explain. (Which is honest, but does not look good!)

2- List it. But when the form asks if the company may contact this employer - check NO!!!! If asked why not, just say you will do not believe you will have a favorable review. (It's honest!).
