I was employed by a large company and dismissed due to a customer complaint. I am commission sales with expenses. Employed one year . do I have recourse?

You are owed severance, unless what you did was really bad. It is extremely difficult to terminate employment without severance. To tell you how much severance, I would also need to know your age and level of compensation. It would be between 3 - 6 months of severance. It is very important that you call me to discuss.
