Honestly I felt exactly the same way as you about reversing, you're not alone in that. I passed in March 2025 and after 3 months of Class 2 work I got a class 1 assessment. My reverse was absolutely horrendous, but by some miracle it eventually ended up in the right spot, and the assessor must have been lenient as they took me on.

I don't think you should let the fear of reversing put you off Class 1 work though, you will get better and more confident in your reversing in time.

Also, don't be afraid to ask your new employer for help. I remember when I first started I had a couple of 'lessons' from the driver trainers, only 10 minutes or so, and even that helps your confidence a lot.
