The players have scheduled a meeting at the Masters tournament in Shanghai next month where they will discuss their demands and what to do if they are not implemented, with both Nadal and Murray refusing to rule out strike action.
Norfolk, Britain's leading wheelchair tennis player, agrees there are too many mandatory tournaments on the ATP World Tour but does not believe refusing to play is the answer.
The two-time Paralympic champion said: "The crux of the problem is the number of compulsory tournaments they have to play.
"The players definitely have a point. You need downtime to recover. It's not just how many tournaments you play - it's the training, the travel.
"The paying public want to see the stars and they just have to come to some agreement, although how they do that I don't know. But I do think strike action is unnecessary."
Norfolk missed out on a sixth major title when he was forced to retire with a suspected side strain during the US Open final against David Wagner earlier this month.
It was doubly disappointing for the 50-year-old because he had dominated the USTA Wheelchair Championships in St Louis a week earlier, beating his great rival Wagner in the final for the loss of only four games.
Norfolk said: "I'm still waiting to find out what the problem is. I'm hoping it's just a strain.
"I was playing so well. In St Louis the results spoke for themselves and I went into the US Open very hopeful. I did get to the final and I defended all the points but I'd never pulled out of a match in my life."
Norfolk is hoping to return to training next week but he will not be back in competitive action until November, when he will contest the Doubles Masters in Holland followed by the Singles Masters in Belgium.
He has made no secret of the fact that a third gold medal at next year's Paralympics in London is his priority, with his whole schedule geared around peaking at the right time.
Applications for tickets close on Monday, and Norfolk added: "It's a fantastic thing for the general public to come and see, a once-in-a-lifetime opportunity to see the best wheelchair athletes. I'd love to be able to play in front of a sold-out British crowd."
