Journalists at the Southern Daily Echo in Southampton, part of Newsquest, are striking from 5-7 January. The NUJ members have already held two 48-hour stoppages over a pay freeze and non-payment of agreed pay minimums since July 2008.
Two days of coordinated action are taking place on 6-7 January at Newsquest papers across the country.
Journalists at the Echo were angered when staff who crossed the picket line were given an extra day's pay per 48-hour strike - meaning many were paid time and a half for working their normal hours.
But a number of those who received the bonus have pledged to pay it into the strike fund, details on their Facebook page: Southern Daily Echo NUJ.
