Bro this is a serious decision, my request is you can hear from us all, but you should decide based on your best judgment.
Whatever worry you have, all are true. But get carried away by news only is not right, as well as, not being cautious is not right.
Women are working these days, be it Govt, private, MNC or NGO, its the same everywhere... a pretty girl, and eyes will trace her. That goes with little humor, attention, touch, threat and also there are people who are having funtime working together as a family. You cant differentiate between organization types, its the people on that place that makes or breaks the name.
She will be spending two third time with work, one third with you. Naturally the association will be bigger and consume her personal time too. If you can accept go ahead.
Talk on loyalty, that always is fluid and easy to pretend. What is more concerning to me is the competition. If she finds two colleagues with same caliber working together one is getting high pay and promotion just because she is compromising with certain individual, your wife can get distrustful very soon, or she can follow the same suite. If she is not hyper career lady, she can accept and manage both home and work. But if she is determined to grab corporate ladder, little chance that she can do in right way.
I am giving some food for thought, decision is yours.
