The Queens Park Rangers boss was reportedly offered a new contract but now faces an uncertain future at Loftus Road.
The 67-year-old was said to have been offered a new deal by the club earlier this season, although that talk has quietened down considerably following the Rs' poor start to the Premier League season.
Redknapp's side have won just once in seven league games and sit bottom of the table.
But the QPR boss says he 'never even saw' a contract in the first place and has no interest in signing one until he can guarantee top-flight survival for the west London side.
“I never even saw a contract,” Redknapp told the Independent. “I had no interest in signing one either. I said to Tony Fernandes that if we stay in the Premier League then let’s sit down and have a discussion.
“Why would I sign on for another two years after this season? If Rangers got relegated I would take full responsibility and I wouldn’t have any interest managing in the Championship. It would probably be the right time to think about looking at someone else.
“There would be no benefit to the club other than to pay me money for walking away and that wouldn’t be right.”
On the subject of walking away from QPR, Redknapp said:
“I have no intention of walking away, not a chance. I’ve not even considered it. I’m confident I can keep the club up, nothing has changed."
