In a remote work environment, it's more difficult for a manager to witness the visible signs of employee stress and burnout and to recognize the signs of overwork. It's all too easy, working remotely, to add another task to an employee's plate, or another meeting, via a Slack message or an email. Work piles up through these informal channels, increasing the time and effort devoted to personal task management and impromptu, low-value requests.
