Taxing Matters
I say it depends on the circumstances. If this misclassified worker did not pay the FICA taxes on his/her earnings then the IRS change in classification and pursuit of the employer will relieve the worker of those taxes and the employer will have to pay them instead. And going forward the employee would be treated properly as an employee, with the required tax withholding, etc.
But you are right that it comes with a risk that the employee may end up being fired over forcing the issue. The law does not protect the employee from retaliation for reporting the employer to the IRS (nor do many states protect the employee for reporting the employer to worker's comp, unemployment, etc). Whether the law should provide that protection is something over which I'm sure people would disagree. But if the employee wants to stick it to the employer, especially when he or she is leaving anyway, and make things better for his/her fellow employees going forward, there would certainly be good incentive to take that risk. If the employee really needs that job and is sure he or she can't get another job out there where he or she would be treated better, then that termination risk may be more than the employee is willing to take. On the other hand, the employer has to weigh how easy it would be to replace that worker going forward. If the person has skills that are difficult to replace or is simply a much better worker than the employer usually gets, the employer may decide to keep the employee despite being ticked off at being reported and having to pay the price of misclassification. Every situation is a bit different.
