How do I handle complex benefits cases and compliance rules?

You can run the everyday work now, which is real progress. It is the tangled cases and the compliance rules that still trip you, and those are genuinely hard. They trip nearly everyone at first, because they demand precision in a field that keeps changing. Complexity is not conquered by memorizing everything. It is handled by knowing where to look and whom to ask. The people who seem effortless with hard cases are not carrying every rule in their head. They have built reliable references and a network they trust. That is a skill you can build too. Start a simple record of the tricky cases you meet and how each one was resolved. Over time that becomes your own map through the maze, and the cases that once stumped you become ones you have seen before. You are not behind. You are in the part where the real expertise gets built.
