Common mistakes to avoid

• Forgetting to mention specific dates of leave
• Not promising to submit a medical certificate when leave exceeds the company threshold
• Excessive personal medical detail (employers do not need full diagnosis)
• Casual language for formal contexts (avoid emojis and slang)
• Submitting the letter days after the leave (apply on the same day)
