When I conduct career coaching sessions, I inform my clients that part of career management is to always keep copies of their performance reviews. They will serve as documentation of their growth, skills, and achievements, and excerpts of comments can be incorporated in a resume or cover letter (a great way to set oneself apart from the competition).
But what happens if a person’s company does not conduct performance reviews? In this situation, an employee should email his/her supervisor upon completion of a large project or whenever he/she accomplished something (streamlining a procedure, saving money/making money, solving a large problem.) The employee should keep a copy of this email (and possibly any response from the supervisor); these will serve as documentation of the person’s growth, skills, and achievements.
