"All My Children" and "One Life to Live" have been placed on hiatus because of a labor dispute with the International Alliance of Theatrical and Stage Employees - Local 52, which represents the online soap operas' crews.
Prospect Park, which produces the two shows, said the hiatus will begin on Thursday instead of June 17, as had been planned.
"We are in a labor dispute with the IA and we are going into hiatus immediately until this is resolved," a succinct note to the shows' cast and crews read.
As TheWrap first reported, I.A.T.S.E. believes the two shows have gone over budget and violated a labor agreement in the process, according to an individual with knowledge of the union's plans.
When Prospect Park revived the canceled ABC program for the web this year, it hammered out a deal with the union that allowed it to pay members less than the standard day rate as long as it did not spend more than $125,000 per episode.
The union believes that on certain episodes, "All My Children" may have more than doubled that figure, triggering higher rates for members.
Prospect Park refuted those contentions in a statement to TheWrap, adding that it could not afford to pay union members a higher wage.
"We believe we have met all contract requirements with I.A.T.S.E, and as an internet start-up, and per our contract with the I.A., we cannot afford, and our business model cannot sustain, traditional broadcast rates," the statement read.
A spokesman for IATSE did not immediately respond to requests for comment.
Prospect Park said it hoped to resolve any issues by August when production had been slated to resume. The company said it had a library of 40 episodes, which is enough to take it through September.
Budget issues were part of the reason that nearly two years passed between ABC's decision to cancel the soaps and Prospect Park's revival of the programs last April.
After Prospect Park worked out a deal to license "All My Children" and "One Life to Live," an attempt to resuscitate the soaps in 2011 was scratched when it could not secure the backing to produce the dozens of episodes a soap airs annually.
When it was broadcast on ABC, "All My Children" carried a reported production budget of $50 million a year.
