Histon boss Alan Lewer has warned the club's contract rebels that it will not be easy for them to find new clubs.
Keeper Danny Naisbitt, Matt Langston, Danny Wright, Lanre Oyebanjo, Nathaniel Knight-Percival and Bradley Hudson-Odoi have all turned down new deals.
All six were left out of Saturday's goalless draw with Gateshead.
Lewer told BBC Radio Cambridgeshire: "People can go on the list. I have spoken to managers at full-time clubs and they can't afford these players."
He added: "It shows you the sort of money that has been paid at Histon over the last few years.
"We have offered the players contracts, some of them increasing contracts and some of them on the same money.

"People out there think it's easy to get another job but it's not because they are in the queue with 3,000 other people."
Lewer said the future of the club could be put at risk if Histon did not look to cut their cloth accordingly.
"If we don't address it now we won't have a football club," he said. "It's happened to Darlington, Weymouth and Portsmouth.
"If we don't address it now we will be in trouble."
And Lewer said he had no plans to bring the six contract rebels back into the first-team picture for Tuesday's visit of Tamworth.
"It will be a similar line-up to Saturday," added Lewer. "The boys deserve their chance.
"The club is bigger than any player and we have got to make that known to everyone out there."
