Stupid EE tricks

We have all had EE’s try to throw off return to work exams before, like the diabetic who doesn’t take their insulin before the exam or loads on candy before. Well I have found a whole new category. I have an employee who is playing with his digitoxin doses before the return to work Holter each time. I am almost considering sending him for a psych exam to see if he is just stupid or suicidal.
