ITV Central reporter Callum Watkinson was caught on camera confronting the man in Centenary Square, Broad Street, after finishing a report.
In the 53-second clip shared on social media by ImJustBrum, Mr Wilkinson said he would "****ing bang him out" if the man stepped behind him again.
The TV reporter was heard saying: "I'm not a higher class than you mate, I'm just trying to do a job – have you got a job?"
The man replied "yeah I do" before the reporter added: "Well go and f***ing do it and I won't come into your workplace and start ****ing with ya."
Mr Watkinson, after being told to "stop being rude", retorted: "If you get behind me again I will ****ing bang you out, do you understand me?"
He continued: "Why don't you go and get a job and then I will come behind you and start behind an idiot? Where do you work? Footlocker or McDonald's?"
Mr Watkinson, who performed a mocking dance, added: "How about sorry for trying to mess up my work? How about that? Do you know how hard it is to broadcast live to half a million people?
"Do you know how hard it is to concentrate? It's quite hard without someone in the background going 'ooooh I want to be on TV'."
