Should you sue if you're fired for theft or dishonesty in the workplace?

On the flip-side of the coin, here's an article from Daniel Lublin, a noted Toronto employment lawyer, who has his own take on employee dishonesty. The article cites the case of Leitner v. Wyeth Canada, which deals with the conduct of mid-level manager who has been accused of fraud over expense reports, the amount in question was less than $500. The judge found Leitner had made an error it, but ruled that it did not meet the threshold for asserting cause and awarded ten months of common law notice. I've attached a link to the article and the case below:
