Around 20% of workers are losing out on sleep because of newbie managers, survey finds

• Workers are getting poor sleep because of rookie managers with little training, a new survey found.
• Over a third of workers have been tempted to quit because of the new manager, per the survey.
• This is because companies often promote senior employees to managerial roles with little training.

Employees experience greater stress and anxiety at the hands of rookie managers who were promoted to their position without adequate training, a new survey found.

Oji Life Labs, a digital learning platform for leaders, published the results of a poll of 2,066 adults on Tuesday — conducted by Harris Research in June — that looked at how new managers impact their teams. Bloomberg was first to report on the survey.

42% of workers said they've had a first-time manager and of that group, 41% said they felt more stress and anxiety as a result of this manager. Some 40% said they lost confidence and just over a third were tempted to quit as a result. And, one in five workers said their sleep quality also suffered as a result.

Harvard Business School professor Linda Hill commented on the poll results in a press release accompanying the report: "In my research, I've seen how strong individual contributors are often promoted to management roles with little or no leadership training, with a 'sink or swim' philosophy.

"It's no surprise that these untrained leaders often struggle in many areas, compromising the productivity and agility of their teams in these very competitive times," she added.

René Carayol, executive coach and author, previously told Insider, that new managers need to avoid micromanaging employees because they lose confidence and trust.

He added that IQ is less important than emotional intelligence, especially because young managers feel they have to be "the cleverest person in the room."

Instead, "their job is to create an environment where other people can fly," he said.
