After the BuzzFeed article and Unicorn Flyers they bumped pay and bonuses by ~20%. This was around 6-8 months ago. From what you're saying it sounds like it wasn't enough.
Maybe that's because these things tend to only happen when there's a serious lack of respect and the employees have noticed. You can't bribe people into thinking you respect them. It just looks like being bought off. Twist the knife a little won't you?
