My employer garnished my enitre last paycheck stating I owed him for a professional conference I attended. I did sign a contract stating I would agree to payroll deductions if I did not hold an informative meeting with my fellow employees informing them of the conference content within 3 months of return. I was terminated 9 months later for other reasons however there was no discussion of deductions or the garnishment would take place.. It is my understanding even with permission or judgement it is a federal law that a paycheck cannot be garnished below minimum wage in the state of MN the law as I understand it states no garnishment can be more than 25% of my paycheck. Can I sue my employer for my wages?
