In international organisations there are usually separate scales for employees with dependent (ie unemployed or partially employed) spouses and also dependency allowances for children, including education grants which enable parents to send their children to private schools and universities with up to 75% of tuition (some ceilings apply) covered by the organisation.

There is 16 weeks of fully paid maternity leave and 4 weeks of paternity leave. There is breastfeeding time allowance until the child is 12 months old. You can arrange to work from home or part-time. You can take unpaid leave and come back after 2 years to the same position, especially when you have a permanent contract

But you can not negotiate the salary, promotions usually take years and there are no bonuses.
