Journalists at the Newsquest-owned Southern Daily Echo in Southampton and The Argus in Brighton struck on Tuesday and Wednesday of this week.
In Southampton, NUJ members have set up a blog publicising their fightback.
It says they are striking to highlight “the disparity between how the management of Newsquest treat themselves and the staff who actually produce newspapers like the Southern Daily Echo, despite dwindling staff numbers, pay freezes and ever increasing hours”.
Journalists in Brighton are striking for the same reasons, and to stop jobs from their local paper being moved to Southampton.
Strikes are brewing across Newsquest, which owns papers throughout Britain, with ballots at Oxford, York, Bradford, Bolton and Blackburn.
