Most of my coworkers are younger than me, there are lots of people in their early 20s.
Some are genuine and even explain me things I don’t understand.
Then there are the immature ones who only care about gossip. I don’t like working with them.
I’m doing a one year certification to work on a related field and I already know the group I’ll be working with. If it doesn’t work I can always look elsewhere but I’d prefer staying.
Learning won’t be a problem, training on the job with the mature, genuine ones won’t be a problem.
The problem will be the childish ones that claim they’re willing to help only when the manager is present to do the opposite when he disappears, something that has happened before. In this group there are 2 young girls that are very loud and lazy.


Make sure to be transparent on who did what, don’t take any responsibilities for others. They will either get into trouble and learn to cooperate from there on or not. Things might work out fine anyway, just focus on your own part. Prepare interfaces / connecting parts to their work if they can’t manage to do it, but don’t do their work.
Stay polite but honest. Don’t engage in topics you don’t like. Tell them you don’t care about other peoples alleged / perceived lives. Keep things work related if there is nothing else to talk about and just stay silent otherwise. This won’t be the last time you’ll have to work with people you don’t like or have nothing in common with. Maybe y’all will still find something to talk about after some time.
