Why Grammar Matters More Than You Think for Your Career

A study by Global Lingo found that 59% of consumers would not use a company that had obvious grammatical or spelling mistakes. In a professional context, every email, Slack message, and report either builds or erodes your credibility.

The Hidden Cost of Grammar Errors

Grammar errors in professional communication lead to: misunderstood instructions, lost deals, reduced trust, and slower career advancement. A CareerBuilder survey found that 58% of hiring managers identified grammar mistakes as the top reason they'd dismiss a candidate.

Common Mistakes to Eliminate

  • Its vs. It's — "It's" always means "it is" or "it has"
  • Their/There/They're — Possessive, location, contraction
  • Affect vs. Effect — Affect is usually a verb, effect is usually a noun
  • Loose vs. Lose — Loose = not tight, Lose = to not win
