Those in the field: workplace assistance towards MS? Hi everyone,

 I'm currently an undergraduate studying for my BS in Env. Science and am unsure of whether or not to go to grad school right after or enter the force. Graduate school is something I am interested in, but I've heard certain professions often assist with going back to get a Master's (like teaching). 

Is this practice common for those in consulting, particularly in the US? I could see how entering after undergrad is more convenient, but a chance of not having to pay is appealing.  Thanks!
