Occasionally I find someone in a management position who thinks errors will always “happen”.

The implication is that errors are just part of life and we (particularly me) need to just learn to accept it and stop getting so worked up about it.

Disagree. Strongly.

First, there is ALWAYS a better way, but we rarely find it unless we care enough to search for it.

Second, the manager (if the word even fits) who tolerates errors always gets more. Spoken or unspoken, the message of low standards and mediocre expectations gets out.
