If you are a manager, would you accept that from a subordinate who failed to do their job successfully? The nature of work is that it's not a cleanroom lab or a business school case study; lots of difficult and unfair obstacles exist, and your job is to overcome them. To me, that defines 'job' like the sea defines 'sailor'. You're very lucky when that isn't the case. Realistically, there is some judgment involved and matters of degree, and there are limitations, but the best people find a way using the resources they have.
