True, but on the flip side the contractor gets paid per hour (unless they're daily), whereas the salaried employee has no idea how many hours he/she will work. It's not said in interviews (although "this is not a 9 to 5 shop" is common here in NYC). It's also not written in the employment contract. It's a wildcard, and gets worse due to instability in the environment or team competitive culture or crazy upper management or a million other things.

"this is not a 9 to 5 shop" - this just gave me flashbacks.

Most salaried people have 7 to 9 holidays per year, and if you’re lucky and highly paid, maybe another 4 weeks paid time off. 6 weeks of paid time off divided by 52 weeks is just 11.5%, and that probably puts you in top 10% of the population in terms of paid time off.

Only in the USA - I had 30 days when I joined part of Relex in the UK

But contractors do get paid overtime.

ha ha ha ha ha! Long ago companies figured out to pay by the "work unit", and unless you are working 50% to 100% more then your paid time you are under performing and at risk of being fired.
