The Grecians currently sit eight points from safety towards the foot of the table with just seven games of the term remaining.
But Tisdale, who chose to stay with the Devon club despite interest in his services from elsewhere following Exeter's eighth-placed finish last year, has stressed he will remain loyal to the club where he has moulded his reputation as a manager.
He told the Express & Echo: "I chose to stay here when most people said I should have gone. I wanted to stay because of the type of club we have here. I made the decision to stay knowing full well that even if we have a difficult time, I'm still in a place where I can enjoy my life.
"There is an upbeat, positive nature to this club and I go to work upbeat and positive. One day I may leave, but if I do I know I will be going into a very different working environment.
"At the moment we are in a very difficult position, but there's no shame in it. Just to compete in League One we have to over-perform. Every week we are underdogs but that hasn't made me think we cannot do it."
