> Vault's 2018 office romance survey received 654 responses from professionals in a number of industries. Approximately 70% of responses came from the Law, Banking, Accounting and Consulting professions. A further 7% came from professionals in the Technology sector.

> Have you ever had a fling with a colleague, hooked up with a coworker, or met your significant other through work? We want to hear about it (anonymously, of course!) in our latest Office Romance Survey, our most popular study which has been featured by Forbes, Newsweek, and NBC.
