Sweden gave me a probation period on my first contract too. We hedged exactly like Mei described earlier, with a shorter lease, but it turned out unnecessary. What I'd actually recommend is asking your manager, around the halfway point, how things are going. Mine was surprised I asked, and it gave me the reassurance I'd been waiting for without knowing I could ask for it.
My contract has a probation period where either side can end things with almost no notice, and coming from somewhere with strong protections it's making me anxious about signing a lease or committing to anything. Is this just normal and I'm overthinking it, or is it as precarious as it feels in the first few months?
