Thank you for your question. What you have described is not a valid reason for dismissal. You have been wrongfully dismissed and you are entitled to severance. In addition, you may be entitled to additional damages given the manner of your dismissal. I would encourage you to visit the severance pay calculator our firm has developed to see what you are owed (www.SeverancePayCalculator.com). I would also encourage you to call us and set up a consultation with one of our employment lawyers.
