Lots of employees here have bought into this company spread propaganda that job hopping like in the US will make you unemployable in the future.
As the employees get older and get tied down with families and homes and also Job Stockholm Syndrome they're less likely to shop around for new jobs so the savings on salaries on seniors being paid below market are huge.
And afaik, large companies and large successful projects tend to have more stable core team behind them.
But is that ultimately true? It feels to me that the companies hold the power to make that true, regardless of the propaganda. So even if you try to job hop, after a certain age they have all the power to make you unemployable. Am I wrong? (I hope I am)
I think constant job hopping is bad in 3 situations: 1) If you work a non lifelong-learning job. 2) If you work a job that is mostly industry-specific relationship based. 3) If you are jumping around to different job roles entirely, where you never really become exceptionally talented at any single role.
My general rule of thumb for deciding when to job hop is when I feel as if I've stopped learning new things.
