NUJ union members at Newsquest Cheshire and Merseyside were set to strike for two days on Wednesday 14 September and Tuesday 20 September.
The journalists voted unanimously to walk out.
After the first day of action they will also start an indefinite work to rule.
The strike is in response to Newsquest’s plan to impose five compulsory redundancies.
The strikes will hit the Warrington Guardian, Northwich Guardian, Sale and Altrincham Messenger, St Helens Star and The Wirral Globe.
