I have been playing this nation for over a year now and have been wondering how to raise my employment rate, considering it's always steadily dropping.
Generally, the more corrupt your nations is, the lower the employment; you can see that here. So, to increase your employment you most likely need to decrease your corruption. How to decrease your corruption you may ask? use this. You can still have both high employment and high corruption but it is up to you on how you can achieve such feat.
