………………………………
It is permissible for you to work if your husband agrees to that and the conditions are Islamic, in regards of transportation and the whole environment.
The problem is that you have to assess your children’s situation. If they will lose by your absence, being with them is a priority. But if they go to school and while they are in school you are away by when they are at home you are with them and you are not tired to serve them and watch over them, this is OK.
And Allah knows best
