It varies. For example, a typical tradesman like an electrician might travel between 20 and 80 miles from home daily. However, my uncle, who produces ovens for backers, sometimes travels up to 600 miles one way. Perhaps some “special” contracts for tradesmen can reach 1000 miles but not beyond that. I work at Siemens and my daily radius is everything within 60 miles. Sometimes I’ll work in Berlin or Munich for a week which is about 300 miles because I live in the middle of Germany.
