sometimes you can do both at the same time, its more of a spectrum you see

addendum:

aw fuck i didnt see the title at first, sorry about that op.. i had, at one place: abbrasive dust in some parts of the plant, corrosive fumes at others, a carcinogenic dust workstation with improper handling by one coworker, two lasers in another room... on some level it was nice to see all that i guess. but in retrospect i should have asked for home office instead of becoming the their girl for any job under the sun to keep shit running smoothly.... how was your experience so far?
