They don't care about the fucking dress code. That was just Bush being an asshat. They care about your leave bidding, being able to alter your schedule at will, being able to make you work credit/comp instead of OT, being able to ignore your lunch break, being able to force you off on holidaysetc. Pretty much everything that costs them money and their ability to independently manage.
And that's not even getting into the basic employment rights shit like TRBs, return rights, nest, hardships, etc.
You guys really are summer children and don't realize it.
