They are many signs, but when you start asking this question, you are very likely already burning out. I have a few burnout coworkers around me, the signs I've observed: - complaints about the system/process/workload, - always busy but no fruitful deliverables, - memory loss/slow reaction, - bad tempered, easy to become anger when hearing about different opinions, - worse immunity but not taking sick leave.
