Instill confidence. Reinforce your certainty that they’ll regain their old form. Take a long-term view. Say, “In the three years you’ve worked for me, you’ve set a high standard. I have no doubt you’ll bounce back and set an even higher standard.”
Challenge them to persevere. Rather than speculate with employees about how long their slump might last, note that this is a test of how they’ll overcome it. Encourage them to stay on course and keep their spirits up. Explain that slumps are inevitable, and they’re really a gut-check. This reassures employees that you still have faith in them.
Ask for input. You’re not a magician, so don’t try to figure out by yourself how to end the employee’s slump. Instead, exchange ideas in a supportive way. Ask, “What steps have you tried already?” and “Can you point to any reasons this is happening?”
Turn slumpers into mentors. Ask the slumping employee to serve as a mentor to a new hire. This enhances the veteran’s self-esteem while helping the rookie learn.
