Villas-Boas also denied his widely-publicised interview with a Portuguese radio station last week had upset the Blues hierarchy, amid reports they had taken exception to his candour.
The Chelsea boss stood by every word, insisting the broadcast needed to be heard in its entirety to accurately portray what he said. It was Villas-Boas' reflections on his job that sparked the most headlines and he said: "There is a doubt over the future that lies in every single job in our lives, in mine and in yours."
He added: "Everybody is more or less under threat with positive or negative results."
Prior to last week, Villas-Boas had repeatedly insisted he had the full backing of Roman Abramovich to complete his three-year "project" to revamp Chelsea, despite the club being in danger of their worst season since the Russian's takeover almost nine years ago.
Villas-Boas sidestepped questions about whether his future would be determined over the next fortnight, which sees Chelsea play two crucial Barclays Premier League games in their bid to get back inside the top four as well as an FA Cup replay and Champions League second leg.
"They are key just because we can be out of or continue in two competitions," he said ahead of their league game at West Brom.
Asked if March was a defining month, he added: "It can define a 'trophyless' season for Chelsea, yes."
The pressure on Villas-Boas has not exactly been eased by reports continuing to link former mentor Jose Mourinho with a return to the club.
Villas-Boas said: "The only place where Jose's shadow isn't lurking is Barcelona. It's everywhere else in the world. If you can train a manager to be the best in the world, everyone wants him."
