Your bank will file a report with FinCEN that says that you withdrew (or deposited, or transferred, or whatever) the money. They can/will also separately report suspicious transactions, including patterns of transactions that seem designed to evade the reporting requirements.
Not sure. Apparently walmart you can cash up to 7500 for half the year and 5000 other half for tax return purposes I guess. Still maybe you can get paid weekly instead of biweekly.
