[Red ones]

What tosh.
So, you run a small business churning widgets. You created this company from an idea you had at the kitchen table. You know how to churn widgets.
The day arrives when you need someone to run your website, your social media, to do your graphic design, to write your user manuals to be your finance director etc.
You can't employ them because you don't know how to do their job.
Stupid argument. You employ people BECAUSE you can't do their job.

Thanks for dissing how I got to my job. I don't know anyone who has the skills to do all the jobs I have to manage people doing. One moment it might be painting a wall (I could do that poorly), electrical installation, replacing an industrial direct fitted gas burner, installing and maintaining office air conditioning, road surfacing, marble floor laying, signage design, choosing furniture or a coffee machine, space planning or financial forecasting.

Showing an employee that you could do the job better only does the employee you don't trust them. Choose the employees for talks you can't do, recruit for your weaknesses and then show trust and care.
