If you're not comfortable with taking on risk, busting your ass, and doing anything it takes for a very small CHANCE at hitting it big -- then don't work for a startup. Period. There are many other software / IT jobs right now -- no need at all to work in startup land. But don't try to fuck it up with this "union" nonsense talk. All you'll accomplish is dragging down those who are truly talented and deserve to be there.
If you do go that route -- get educated. Pay a lawyer a few hundred bucks to explain the docs you are about to sign which grant options, have a vesting schedule, etc. If you don't, you're a retard and you deserve to be taken advantage of. But this "unionization" talk runs completely counter to the very DNA of a startup. Face it -- some people are willing to work 80+ hrs / week. If you're not -- fine. But don't fuck it up for those who *choose* to do so and try to out-work others to gain an advantage.
