What is a bigger threat to our economic system: Golden Parachutes or Collective Bargaining?

As the value of the American Dollar is once again higher than the value of the Canadian dollar, it begs the question as to which is a bigger threat to our economic system: Golden Parachutes or Collective Bargaining. On one hand, you have high-level executives who receive amounts in the millions to mismanage a company, only for those organizations to turn around and request a bailout or some other form of financial assistance from the government based on taxpayer dollars. On the other hand, you have a group of people in a union that set rates and wages which may be higher than comparable jobs that aren't unionized, leaving the option for employers to either move the jobs out of state or out of the country. Or do you happen to think that two wrongs don't make right and there should be restrictions on both? Do you have another idea? Please share and discuss!
