i need advice on the state of employment in the nation. What is the best way out.

I heard that NYSC now has like 3 or 4 batches a year now and each batch may be thousands of youths. Then I heard many companies are send out many of their employees in thousands and those left were combining job functions leaving very early and come back late everyday and many take home cannot take them home. I checked some of the jobs sites what I saw made me ask this questions. Id those employed are not 10% sure of there jobs what happen to those still looking for one?
If those inside are taking up 3 or more job functions together just to take home what cannot take them home
What can the youth do kindly advice
