Pro tip:
Half of them really are incompetent. The other half are just pretending, because they discovered that once they demonstrate more than the minimal level of competence management will never stop demanding things. Also, competence is almost NEVER rewarded. Performance appraisals are a complete joke and everybody knows it.: @1xjt+1iPpL4TV
Very useful advice. How many times have you regretted demonstrating that you know something and then got even more work?
