what policies do major corporations have for married male employees regarding travel with women coworkers?

Answer 1

For cost effectiveness they have to share the same Hotel Room. Other than that there really no policies. You do have to Dine together to keep paperwork down.

Answer 2

What kind of "policies" do you have in mind?
Major corporations (and minor ones) assume their employees are adults, and treat them as such. Other than having a general policy against sexual harassment, there is no "policy" regarding travel with either male or female coworkers. There are also no companies that make any "policy" distinctions between married and unmarried people, males or females. All employees are expected to act responsibly and in the best interests of the company at all times -- that's it.
If you're thinking companies should have some kind of prohibition against married men going on a trip with a single woman -- that's kind of ridiculous. And discriminatory. And unnecessary. Business trips are for business. If there's any "funny business" going on, the person doing it is just as likely to do it at home as they are on a trip...

Answer 3

Typically with any travel situation whether male-female, male-male or otherwise each employee is separately responsible for making sure that they get on the plane and that they make it to their hotel room. Every employee gets a separate room regardless of the sex. The only thing that might be shared is a rental car if both employees will be staying in the same hotel and attending the same meetings.

Answer 4

The policy is the same if you're traveling as if you were working in the office.

Answer 5

Depends on the company, but likely they would assume you have separate hotel rooms and act like decent people and not do anything completely stupid in an expense-account drunken fit.
