Unfortunately under the laws of all states in this country, an employee is terminable at will unless there is a written agreement to the contracry or the employee is terminated based upon discrimination sbased upon gender, sexual orientation, religious beliefs and the like.In your situation, it would appear that even though your employer may have hired you under some false pretenses, you really do not have any legal recourse in the event you are terminated based upon being a seasonal employee.I would be proactive by actively looking for another position if you are not happy where you are.
