In Italy, for technical jobs, traditionally a new employer should offer your 10% more on your yearly gross. Conditions apply of course, such as being already above the average pay for your position and experience, or having already changed job recently, but it's way more than you usually would be able to bargain for a raise (idk why employers are allergic to pay raises, but replacing you when you leave with someone more expensive apparently is ok, despite the new hire requiring time to get up to speed).

Nowadays it works less for roles that aren't in high demand, and even then they try to low-ball you whenever possible, but it's still better than fighting for raises.
