Consultant or Employee?

I recently met with a design agency to explore their challenges and discuss how we may be able to work together. During our conversation they made reference to having ‘consultant fatigue’ which has made me question how the land lies for consultants.

I’d like to hear how owner-founders and leaders feel about engaging a consultant or coach to help them develop and grow their business or address other challenges. What are the preconceptions, and are firms more interested these days in hiring such experience into their firms on an employed basis rather than consultative?
