Can a company discipline an employee for taking absence without leave if that worker could be suffering from mental illness? Just a few weeks ago, on April 27, the Supreme Court ruled against Hewlett-Packard Japan Ltd. in a case that posed precisely this question.

He became obsessed with the idea that the gossip was continuing, imagining he could hear them talking about him 24/7.
