A BBC investigation suggests more than half of City of London workers have seen or experienced bullying in the workplace.
City workers complained of sexism, racism and aggressive behaviour
Of the brokers, traders, analysts and dealers surveyed for BBC Three's The City Exposed, 56% had seen evidence of bullying or discrimination.
Complaints ranged from racism, sexism, violence, verbal abuse and a general "school yard" mentality to unequal pay and career blocking.
The survey follows a High Court decision to award nearly £1m damages to a City worker who complained of a culture of bullying and abuse at his firm.
After the damages were awarded to Steven Horkulak in July, the firm which represented him said the City should "take a good look at its practices and culture".
But the BBC survey of 331 men and women in the Square Mile carried out in September found 31% claimed to have suffered bullying or discrimination themselves.
Half of the respondents described their workplace as hostile, aggressive or stressful.
The programme's producer, Joanna Burge, said: "Everyone imagines the City to be a pressurised environment but this shows just how pervasive the atmosphere of bullying and aggression is in some quarters."
She added some "former high flyers" had been forced to quit their jobs because of abuse.
The City Exposed is on BBC Three at 2100 BST on Thursday.
