My hours were cut by 20 hours per pay period because of lack of business.Then i was let go for restructuring and paid accordingly. but two days later a board member took over my job and was paid for seven hours per day.Isn't this wrongful dismissal?

Yes, what you have described is a wrongful dismissal and you are entitled to severance. 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 free and confidential consultation with one of our employment lawyers.
