The tongue-in-cheek generator was created after research of 2,000 office workers which found three in five have ended up losing their cool at work.
The top thing to cause people to lose their temper was unreasonable colleagues, followed by a big workload and making mistakes.
Third in the list was computer issues, with 22 percent most likely to lose their cool over technology.
But 45 percent admitted their colleagues are more often the cause.
The research found other things which make worker’s blood boil are smelly lunches, colleagues doing online shopping and dirty toilets.
A spokesperson for Andrews Air Conditioning, which commissioned the study and tool, said: “We’ve all been there. Desperate to say what we really think but bound by being professional and polite.
“So, we think this tool is a great way to vent your frustration while still keeping your cool.
“Workers can turn to the tool if struggling to word an email in a professional manner to ensure they don’t later regret what they said.
“We know how easy it is to lose your temper, particularly in the workplace whether it’s colleagues, clients or customers, but it’s important to think before acting rash.”
The study also found 69 percent wish there was a way to turn what they actually want to say into more professional language.
And 60 percent would like to lose their cool less frequently.
A quarter admitted they often regret it when they see red in work and as a result 23 percent have had to take a break, 18 percent have confronted someone and 16 percent have even shouted out loud.
On average, workers lose their cool twice a week, but 59 percent believe their colleagues do so more frequently than them.
But 43 percent admitted to making rash decisions when losing their cool at work, with 11 percent walking out and one in 10 writing a passive aggressive email.
Further consequences were revealed as being disciplined, ruining a relationship with a colleague and even one in 20 being fired.
To try and stop their blood boiling, 29 percent have walked away from a situation in the workplace, while 13 percent have simply made a cup of tea.
While 11 percent of those polled via OnePoll have counted to 10 before reacting.
The spokesperson for Andrews Air Conditioning added: “The study shows that cooler temperatures help people stay calmer and react less rashly.
“We believe at least if it’s temperate in the office it’s one less thing to stop workers going over the edge.”
