Compensation has become very complex over the years. While most people understand their pay the rest is usually where employers cheap out, things like insurance, sick pay, long-term provider care, pension contribution, tend to be worse for my friends who also work in IT but in non-unionized workforce.
I understand that in the US unions are often seen as a burden, rather than a constructive partner, so I hope this one will help to improve the image of all unions as well as improve live of Googlers.
