With open floor plans, "you feel like you're constantly getting interrupted all the time and it takes you twice as long to complete whatever task you're working on," Cain explains.
While this is a key issue for all workers, it's even more pronounced for introverted employees.
"Introverts react more to stimulation," she says. "If they're out in an open floor all day long with lots of noise coming at them and interruptions... it makes it neurobiologically that much harder to get their work done."
In fact, constant stimulation leaves introverted employees feeling drained and unengaged, says Cain. "For introverts, we feel at our most alive and switched on when things are a bit calmer," she says.
However, Cain notes that she's not against all open spaces. In fact, she supports the idea of companies creating "social spaces" where employees can choose to work in that kind of environment, mill around, connect with one another and get out of the office.
"That's great as long as everybody at all times has access to their own private space," she says.
But even that has its limitations. Often, when companies do utilize private spaces, employees have to sign up for them at least a week in advance and the rooms are almost always completely booked, says Cain.
"If you can't get the space when you need it then it's not effective," she says. "If it were up to me I would abolish open plan offices."
