A total of 300 people working in Wall Street and the City were surveyed by Orchestria, a company which makes software to enforce employees to use network resources in accordance with company policy and international regulations.
The research discovered that more than 60 percent of respondents in New York thought that it was right that their employer should monitor their email. By contrast, only 38 percent in London supported their firm's right to monitor email.
Employees in Wall Street are under the heaviest scrutiny. Almost three quarters of respondents thought their email was already monitored, compared to 62 percent of City workers.
Only 28 percent of employees outside finance in New York believe their email is monitored.
However, New Yorkers are more likely to try to dodge email monitoring. Sixty percent admitted that they had sent something that they 'didn't want their employer to know about' using webmail.
This compared to 42 percent of London respondents. Or maybe City workers are better liars when it comes to market surveys.
More than seven out of 10 Wall Street workers admitted they had received an email that broke corporate or regulatory policies, compared to just 36 percent of City employees.
Outside finance, the two cities are much closer on this question with 52 percent of New Yorkers and 57 percent of Londoners admitting to receiving emails that broke corporate policy.
"Regulating electronic communication is not just a problem for the heavily regulated sectors such as banking, finance and insurance," said Zeus Kerravala, senior vice president of enterprise research at analyst firm Yankee Group.
"We are seeing a shift in the market as companies outside the heavily regulated sectors realise the problems presented by the accessibility of communication tools such as email, and the possibilities this presents in terms of inappropriate employee behaviour, loss of intellectual property and damage to corporate reputation."
