They aren’t. I’ve seen this argument rehashed a thousand times - “we arent estimating time, just complexity so we can estimate how much we can do in a sprint. which is two weeks. wink wink”
Sadly, if you avoid the extra steps and say "I think this will require 10 working days", some manager will reply "are you absolutely 100% sure that it couldn't be done in 9 working days?".
For some reason, calling it "10 story points" does not provoke the same instinctive response.
