West Brom players are angry that a proposed £15,000-a-win bonus has been scrapped in favour of a £50,000 one-off payment if they survive in the Premiership.
A source close to the squad said: "Everybody is very unhappy. Nobody is being greedy here.
"They just want their proper rewards for doing so well. But the club's stance seems to be that this matter is non-negotiable."
But manager Gary Megson, whose pay has just doubled to £10,000 a week, has clamped down on any dissent.
He said: "Nobody is going to get rich at West Brom's expense. If the club does well, the players will. If not, not."
