Pobol y Cwm cast members have demanded talks with S4C over the decision to axe the soap's Sunday omnibus.
Earlier this month, it was announced that the omnibus will be taken off air from September this year as part of a number of cutbacks to the long-running Welsh show.
Pobol y Cwm is produced and largely funded by the BBC, but S4C pays for the weekly catch-up broadcast.
On behalf of the drama's cast, the actors' union Equity has released a statement requesting consultation over the decision, which will affect their contracts.
The statement read: "There had been no discussions whatsoever between Equity and the BBC and S4C about the costs of transmitting the omnibus before the S4C statement was made. We would welcome such talks and call for them to commence immediately.
"The omnibus has been extremely popular amongst non-Welsh speakers and has been a unique uniting factor for the two languages - it has also brought new viewers to the channel."
Speaking in response, S4C's director of content Dafydd Rhys told Wales Online: "In line with common practice, the programme producer is the appropriate party to discuss contractual arrangements with their staff and employees.
"However, S4C is more than happy to explain the background to the reduction in S4C's budget, and the reasons behind S4C's decision to bring the weekly omnibus to an end while ensuring that episodes are available to watch online via our on-demand service, Clic."
S4C is aiming to make £1 million in savings to the soap's costs. Other changes will include the number of weekday episodes being cut from five to four from January 2015, and the show being taken off air for two weeks a year.
