Most people who need leave or an accommodation at work never ask for one, and the reasons are almost entirely about fear rather than law. This article explains what actually happens when the conversation starts, which words trigger which legal obligations, and why the employee does not need to say any magic phrase. It walks through the three overlapping systems that can apply to the same request, the interactive process that the law requires and most employers run badly, and the certification fight that follows. It uses a hypothetical restaurant manager with a new diagnosis to show how a single email changes the legal posture of everything that follows. It explains what an employer may and may not ask, what undue hardship really means, and why indefinite leave is the hardest request to win. It closes with the retaliation problem that makes the whole conversation feel dangerous and the documentation that makes it survivable.
