Man that's a slippery slope. I dunno what I'd do! That really stinks you lost your job - but God always knows what's best. Perhaps it wasn't the best environment? Huh.
When I worked in a mortuary I refused to get all the vaccines they wanted me to get. Hence, I decided not to go in the rooms you needed to have the vaccines for. But Thailand is much prettier than an embalming room...that's a tough choice! Course, being ill upon your return and working harder to get well again would really stink. I'd think it'd be easier to work to get the vaccines out of your system than any number of things you might contract. Right?
