NUJ members at Trinity Mirror's Media Wales, which publishes the Western Mail, South Wales Echo, Wales on Sunday, and other titles, are demanding immediate talks with management after plans to cut 22 editorial jobs were announced.
Under the management proposals, 10 district office staff, eight production journalists and four members of the sports staff would be made redundant.
The NUJ chapel members unanimously passed a motion criticising the pay packet of Trinity Mirror chief executive Sly Bailey. It reads: "This Chapel expresses shock at the scale of editorial cuts being proposed by the management of Media Wales.
"While recognising the especially challenging nature of the trading climate in Wales, it is determined to do everything possible to protect the jobs, wages and conditions of its members, as well as the quality of our products.
"The Chapel instructs the Chapel committee to enter immediate talks with management to secure the best possible outcome and authorises the committee to take whatever action it sees fit in association with the union's national officers, including organising a strike ballot.
"The Chapel also expresses its outrage at the obscene level of remuneration enjoyed by Trinity Mirror chief executive Sly Bailey - £1.7m in 2010 - and her fellow directors and calls on them to volunteer for a pay cut."
Father of the Chapel Martin Shipton said: "We shall be entering an intensive period of negotiation with management to mitigate the damage to our members' livelihood and the newspapers we produce.
"Members are especially angry that while they are expected to lose their jobs or in some cases take pay cuts, Sly Bailey and her fellow directors continue to be paid obscene amounts of money."
