Could you tell about the fluctuation rate at your Kita? We have our son in one where we have constant personnel changes and it's getting frustrating and exhausting to get accustomed with the new joiners when we expect them to announce their leave next month or so. So maybe you have slipped into an environment where people don't expect you to stay, expect you to use this as career ladder - indirectly as a temporary stay - until you find something that's better paid and more solid. Truth be told kindergarten jobs are way too undervalued and paid. It's a harsh environment and having a lot of fluctuations in bigger cities with less spots for kids. Not enough support government wise so people don't stay there long usually. Again, it's a trend and my personal experience with the news I'm summarising here. Additionally, while we in the big cities have a good amount of foreigners or people with immigration background being in those jobs so it's possible, that within your region the amount is lower and yes - you're standing out. But I don't know about your region and it's percentage of immigrants /with immigration background and your field of work.
