This should make for some scandalous water cooler chats
A survey conducted by group Yellow Octopus has revealed just how many of your co-workers are doing the dirty in secret.
And it's a lot more than you might expect!
In the survey it was revealed that 11% of people who took part had hooked up with a co-worker in work, while 4% said they'd done the deed with a non-employee at work.
However, don't worry about walking into an office you think is empty and seeing something you really don't want to see, because most of the action (72%) takes place outside of office hours.
The study also included other office's no-no's such as: How many people have been caught sleeping on the job, the most offensive thing someone can do in the office and strange reasons people have been fired.

While the graphic below shows the amount of people who have fantasised about having a sex with a co-worker at some stage.

Clearly millennial's are a lot more professional than their lustful predecessors!
Or maybe they're just more comfortable with lying...
