Employers hand out bonuses to incentivise enployees to stay. Employees do unpaid overtime to incentivise employers to keep them. My point is that they are fundamentally similar concepts. It's great that you're in a position where your employer wants to incentivise you to stay around by giving you bonuses yet you don't need to do overtime to keep your job. I'm also in a similar position. Some people aren't, and this has nothing to do with European work culture or work ethics. It's supply and demand.
