The Cottagers are without a win since the opening day of the Premier League season and are currently sitting third from bottom after a weekend home loss to Cardiff.
A section of fans barracked Jol following their latest defeat, and the Dutchman shouldered the responsibility for the loss.
However, Ruiz insists that the players are not looking for Jol to depart.
"We are all in it together. He's having a difficult time because everybody blames him for the results," the Costa Rica international told the Fulham Chronicle.
"But we're a team and we can and will change things.
"He means a lot to me because he gave me the opportunity to come here.
"He likes to talk to the players and to motivate us, especially when we have a difficult situation. It's a difficult situation, but the season is still young.
"Hopefully we will get a good result next week.
"It's going to be a difficult game. We know we need to win."
