@buckeye: there is no time for a notice. It's "We have a job take it or we move on."

@Lee the Union does not compensate you, your company does. The union negotiated the terms of employment including per diem and travel reimbursement. You get perdiem whenever you're in a zone that has perdiem, Zones will be explained to you when you get hired. if you'rein a zone that qualifies for a hotel reimbursement; you get the room (keep it reasonable) they pay you back.

When I was hired I reported to the company, not the union. I didn't meet with a union guy until a month or so after I was hired. Each local is different.
