The Beef Plan Movement says the Minister for Agriculture has failed to deliver during beef talks.
The group has rejected the deal put forward last week following lengthy discussions.
Protests have resumed at a number of meat processing plants - but they're not endorsed by any farming representative bodies.
A range of measures were agreed following discussions between farmers, industry and Minister Michael Creed.
However, farmers are unhappy that the beef prices were not up for discussion during negotiations.
The Beef Plan Movement says the proposals don't go far enough to deal with the real price controlling measures that factories and retailers place upon farmers.
Meat Industry Ireland says disruptive protests will only do further damage to trading, in a week where a delegation from China are due to inspect processing plants - with a view to approving more beef to export to China.
