Not Very Good
It’s quite commonly accepted that being able to use a computer is an important part of many professional jobs these days, including being a teacher at a modern school.
It’s certainly important at our school.
So when you walk in to your first day’s IT induction and declare “I’m not very good with computers,” you’re basically walking in on your first day and proclaiming to your new employer “I’m not very good at an important part of the job you’ve hired me for.”
Do not be surprised if this adversely affects my opinion of you.
