One of the disqualifying events is if "misconduct" as defined in the statute occurred. An example of misconduct would be theft or insobordination. However, what you describe by itself is not enough to say misconduct occurred but it may be depending on what is in the write ups. My suggestion is to contact a lawyer who can help you get the employment record and to handle the MESC Appeal. You may not think you can afford an attorney to represent you but it may save you two years worth of unemployment benefits.
