The World Service announced last month that budget cuts at the broadcaster will result in the loss of 650 jobs and cost the broadcaster more than 30 million listeners.
The BBC will also close five of its foreign language services as it seeks to find savings of 16 per cent – around £67 million – over the next four years, as set out in last year's comprehensive spending review.
Following the announcement, members of the NUJ demonstrated outside Bush House in London, where the World Service is based.
Speaking to protesters at the time, general secretary of the union Jeremy Dear said the campaign would not rest until the cuts are overturned.
Today marks the final broadcasts for the BBC Portuguese service, the Spanish for Cuba programming from BBC Mundo, and the services to Serbia.
In a report on its website, the union gathered comments from other campaigners from across the world, adding their support to the campaign.
"The importance of the free flow of information in developing and defending democracy is being demonstrated so courageously across North Africa and the Middle East right now," NUJ deputy general secretary Michelle Stanistreet said in the report.
"It is particularly bizarre and inappropriate to witness an essential international broadcasting institution like the World Service being torn apart through short-sighted management and government cuts.
"These cuts are caused by the government slashing funding to an internationally respected and successful broadcaster. Journalists and other BBC employees are rightly angered at the destruction being caused to a broadcasting service of which the UK should be proud."
The public meeting will take place on 15 March in the House of Commons.
Meanwhile an oral evidence session has been arranged by the Commons' Foreign Affairs Committee, which is holding an inquiry into the cuts called 'Implications of the BBC World Service Cuts'.
The session is scheduled for 9 March where witnesses due to speak will include Jeremy Dear as well as director of the BBC World Service Peter Horrocks and Richard Thomas, chief operating officer for BBC Global News.
"The session will focus on the effects of the changes announced by the World Service on 26 January, including the closure of 5 language services and the ending of radio transmissions in 7 languages, including Mandarin Chinese and Russian," a description on the inquiry webpage says.
"It will also look at future funding arrangements for the World Service."
