Working overtime long term
Before burnout itself, too much stress and an unsustainable way of working usually manifest themselves first of all as workaholism. If one of your team members starts spending long evenings at work, you should not merely praise them and use them as an example, but be alert and pay more attention to the given employee and their mental condition.
Drop in productivity
As The Muse states, there typically follows a sudden and significant drop in the output of the given employee. If you notice someone going through a period of low numbers, high failure ratio and inability to meet targets, you should beware.
Loss of positive attitude
Loss of energy and positive attitude: this is another typical sign of the onset of burnout. The change is especially visible in people who are otherwise full of humour and maintain a positive attitude even during unpleasant situations at work.
Unwillingness to make future plans
A person who is about to burn out often feels helpless and sees no future in what they are doing. The employee thus no longer takes any interest in what lies ahead, they stop sharing visions with the rest of the team or their manager and have trouble planning anything long-term.
