This is probably facetious, but in America, "paycheck" is a colloquialism for your regular payments from your employer regardless of how they are delivered. Virtually every white-collar worker is receiving payments from their employer via a direct deposit into their bank account, not a physical check. According to this [1] fewer than 7% of employees in the US still receive paper paychecks.

My first job was paid by check, and I know some people that still take them, mostly people that can't keep a bank account (perpetual overdrafters etc.)

The same is true in the US, for the most part, we just still call them "paychecks" even if they're directly deposited.

The point is he's getting paid and is free to quit, it's not slave labor.
