Is it a thing in Denmark where a company doesn't have enough revenue to hire an additional workers? And you're stuck doing the surplus because of a low output co-worker?
I’m sure there are companies everywhere where management keeps an unproductive worker around for whatever reason. But in Denmark at least, they are not required to. All employment in Danmark is at will employment. As long as the reason is not explicitly illegal, employees can be fired for any reason or no reason. As I wrote in a different reply, this is considered uncontroversial because 1. there is usually a severance period of three months, and 2. most workers have unemployment insurance which is both generous and affordable, and 3. we have free, universal healthcare, which means losing one’s job is not catastrophic.
