The London-based plumbing company's workforce were challenged to reveal how much they earn and help establish a fairer system of pay.
MD Charlie Mullins will be shown laying out the challenge at a staff meeting, which generated an immediate collection of emotional responses from staff.
Employees then set off on a period of negotiations with each other alongside a number of job swaps to understand what their colleagues' jobs involve and assess if they are worth more or less than what they are currently paid.
The workforce has to then vote on whether to implement the proposed redistribution of salaries.?The programme will reveal the result of the experiment and if the process has created a better and more productive working environment at Pimlico Plumbers.
Mullins said: "Trying to create a fairer pay scheme where employees reveal their salary to each other was obviously always going to be a risky strategy and I can't say I wasn't a bit worried and concerned about doing this. It certainly caused me a few sleepless nights!
"And I won't pretend that during the process there weren't a few shocks, a few rows, a few tears, a touch of bitterness, and even a spot of guilt once the contents of their pay packets were out in the open. But there was also a lot of happy people and a fair bit of positivity."
He added: "I am sure the programme will generate a fair bit of debate among business owners and employees alike. Talking about pay is one of the last taboos in society and it took our guys a lot of guts to take part. Once they did, they took it very seriously and demonstrated the pride they have in the jobs they do."
