Which Job Should I Choose Government Or Private School ? ? ?

Which one should I choose?

My wife just got a teaching job with a Private school in a neighborhood and shortlist for the UBE appointment in Lagos, She was the only candidate picked for the private school appointment in which they have asked to resume work immediately  if she accept the offer. Although the government (UBE), was said to be for two years, the private school is ready to pay her 80% higher than what the government will pay her.

Right now she is really confused and want me to help her choose which to accept.

I adviced her is to start the private school job and later when the UBE call her she will resign from the private and pick it up.

please help me out, have I suggested right? OR can she ignore the private school after waiting for over two years nursing babies at home? Considering the demand of the private school, and coping with two kids. Please advice me to help her out. She is also running a weekend program at LASU, Ojo.

Right now she as reported to the private school, waiting for the take off of UBE. 

Thanks Peace, I will see to that as you said.
