The video released on 23 August shows the prime minister striding up to opposition MP Pio Tikoduadua, grabbing him by the jacket and giving him a shove.
Since its release on anti-government blog Coupfourpointfive, the video has been viewed more than 120,000 times on Facebook.
Within 48 hours of its release, Fiji police and the Speaker of Parliament launched investigations.
But one of the parliamentary staffers behind the video, Iliesa Raiduduva says he was made to resign over it.
"I was told to come in on Friday and I was also told by the Secretary General to Parliament to tend in my resignation letter ASAP."
Mr Raiduduva, a former administration and civil education officer, is not alone.
Former colleague and cameraman Waisale Tavatuilagi says he was also forced to step down last week for filming the video.
Mr Raiduduva says they both deny they were behind the leak to Coupfourpointfive.
But he says were told by the Secretary General they had breached parliamentary principles of neutrality by leaking it.
"Now before it was sent up to the secretary general to parliament, and the instruction from the secretary general to parliament to delete it. Actually, we delete from the camera where we took it. And we managed to keep a copy for ourselves."
The Secretary General didn't respond to requests for comment and declined an interview with FBC News.
An online crowdfunding effort for the former staffers has raised more than $US3,000 so far.
Leader of the National Federation Party, Biman Prasad, says their firing isn't a surprise.
"This is a very vindictive government. All they do is to protect their cronies and supporters, but their critics and those who disagree with them, face the full brunt of their vindictiveness."
Despite the viral video, Parliament's Privileges Committee on Friday cleared Prime Minister Frank Bainimarama of assaulting Pio Tikoduadua.
Crucially, the committee didn't review the footage filmed by the staffers after government MPs said it may have been edited.
Instead, its members relied on CCTV footage of the incident, which Mr Raiduduva says could have limited its scope.
"And therefore it is very unfair that they did not use that video to determine the fate of the prime minister during the Privileges Committee and yet we are victimised because of that video."
While the prime minister on Friday apologised to Mr Tikoduadua for insulting him, the opposition MP refused to.
By doing so, he opted to be suspended from parliament for six months.
The NFP leader Biman Prasad says they are considering an appeal.
