First question - WHERE!
In the back of the ambulance... that has MRSA and dried blood in every crack and crevice (no matter how hard we actually try to clean it)? I want to wear a Tyvex suit in the back sometimes... not get naked.
In the station? On the rickety old bed that is about to fall apart if you shake it? Can your coworkers hear you? Might your supervisor or another crew member walk in on you?
On the hosebed? With the dirty hose that drags on the ground and has dirt, gravel, and exhaust all over it?
Wait... before we even discuss "where"... lets look at some of the interpersonal relationship issues. If you and your partner become "partners"... can you still work together? Will the company separate you, or tell you to choose which one of you gets to quit? Is it against policy? Might you both get fired?
What happens when you move on... now you get to go work with you ex EVERY DAY. Sounds fun, right?
My workplace has a rule that there is no co-ed sleeping in the bunkrooms. Violation=termination.
My volunteer company has no such rule... and a bit of an "oral history" passed on from generation to generation... I've also shined a UV light at some of our mattresses, and it makes me question sleeping there.
PS... Folks... remember this site is a "family friendly" site... so lets not get too graphic, OK?
