Uzee, once you land here with your wife, she is allowed to apply for any job and work for any company as long as she has your written approval.
Your future (now current?) employer should have nothing to say about it, since it is not supposed to affect them (the employer) in any way.
I think it can be viewed as a plus, since her having a job is allowing your family a better income, and she is busy being productive. I know I view it as a plus when hiring someone here in Qatar, if both family members are can have jobs..
Hope this is of any help..
