No this isn’t a new malady to ask your doctor about, it is a legal disorder that can cost your company.  This article reports a case involving an employer who was sued, partially for being too indulgent.  The employee was a mom with a sick daughter.  Over the course of her employment she built up quite a record of tardiness, leaving early, and absenting herself for entire days.  Her boss was understanding enough to counsel her about it only once in the course of her employment.
Finally, however, he had enough.  During the termination interview he uttered enough magic words about the child’s illness to shift the argument from the mother’s attendance problems to the daughter’s illness.  That led to a lawsuit on the grounds of “associational bias.”
The result?  The company faces a costly trial or a costly settlement.  The story is replete with “damned if you do and damned if you don’t” angles, but if the supervisor had kept his focus to the issue of attendance, perhaps it would have ended differently.
