an employment offer letter is not a contract.

There is nearly always a contract and the business will submit tax paperwork with your compensation to the IRS.

Under the table workers are illegal and on their own

Someone does some digging and figures it out, and maybe five or so years later you get a check in the mail for an amount the lawyers agreed was correct.

Previous pay stubs I suppose. Depending on the employer you may have something in writing. This typically wouldn’t be contract if you’re an employee without a union.

Freedom to treat your employees however you want!

My dude, that’s exactly what I’m talking about. That’s me in fact.

Even if I had a contract it wouldn’t matter as I live in a right to work state, they can fire me at any point without warning or cause.

Having any real employment contract is NOT the norm here.

Non office jobs are more likely to be unionized and this have a contract than office jobs.

That’s the type of thing non W2 self employed contractors or union members might have to lean back on, not rank and file full time office employees.

That’s an exaggeration…
