Integrity vs. Your Job
Without getting too much into what an IRA is, you should know that it’s there to help people build wealth for post-retirement. So, if you hear anyone trying to stick their hands in the metaphorical IRA cookie jar, you know something’s up.
The OP, who worked as a junior accountant at their company, knew something was shady when they discovered that execs were taking funds out of the IRA accounts. Of course, they fired the OP because they couldn’t have someone squealing to the authorities about their blue-collar crimes. We hope the bosses in that company were caught and charged.
