I've always been paid. The one time (in a decade) there was a misunderstanding of a bonus, the owner himself got involved and paid the bonus in my favor.
It's surprising to me that you weren't paid. You're the very first person I've heard of to have that trouble. AA is one of the few MSC companies that you can call nights or weekends if you're having shop trouble and they'll actually answer.
"Let me offer you my definition of social justice: I keep what I earn and you keep what you earn. Do you disagree? Well then tell me how much of what I earn belongs to you - and why?” ~Walter Williams
