A cousine of mine works with a financial services provider in lagos and was assured of a lectering job in his alma mater as a junior lectuerer, though does not know the pay package yet. I want to know if it's advisable to leave his current job in lagos for the lectuering job in ondo state and how much does a junior lecturer take home monthly in a federal school. Thanks for anticipated contributions.

It depends if your friend have passion for lecturing he should go. before you know it he become a professor and earn the respect that this worth more

He should consider which of the jobs will offer him the best in terms of job security and satisfaction and then make his decision.
The fact that he works for a financial coy doesn't necessarily mean he earns a lot

Let him go back to school and teach.
Salary doesn't make a rich man but passion.
