Even salary has drawbacks, they will work your ass to the groundOr don't really have hours at all...
I'm 9 to 5, but there are times when I work 10 hours there are times when I pull up at freaking 10:45.
As some one said though salary (which I am) >>>>>>>> Hourly, being salary means you know you are getting paid for your ideas/leadership/expertise etc. and not just being a body.
I have friends in IB and big law who clock about 11-12 hour days consistently, even on weekends sometimes. I'm salary and there's definitely drawbacks but not as bad as hourly
