Job reference secret codes: what the problem is with "hardworking"

The job reference sounds great.

Only words of praise.

Obviously you've done a really good job.

But with the next point it just won't work.

The testimony may contain an assessment that has been overlooked - a bad one.

There are numerous rules for job references that make a simple text difficult. The employer uses certain formulations to make an assessment that the HR department or a supervisor can understand, but often only for the person being assessed if he has familiarized himself with the topic. Because sounding good and meaning good are not the same thing in the testimony language.
