I live in a country where the unemployment rate is pretty low (2.5%) and the situation is kind of the reverse of what you are describing. Companies are trying to entice potential employees, not the other way around. Give me 6 weeks of paid vacations and do not even think about over-times; you look at me funny and I am gone... there are 10 other companies where I can start tomorrow.
I am now trying to relocate to Spain and it is not like that there - but I get why; because their unemployment rate is really high so employers have the power over employees. But in the US? I am sorry if that is a naive question - I've not been to the US since 2002. A lot has changed, apparently.
