What's the best way to get it through a junior employee's head that their work is sub-standard without completely destroying the relationship? I have a project assistant who botches up so many calculations that I have to spend hours correcting them. Or I send the work back to her, and wait for hours while she plods through it. It's inefficient and driving me crazy. I want to give her a strong message, but I want things to remain civil, too. Advice?
