I recently started a new job. It took ages to get anything and I was so pleased. However, there's one specific duty I'll have to do which I can't physically manage. It involves climbing on stacks of stock to change a card display and bluntly I'm too short and fat. Although ladders are available, the arrangement of stuff on pallets means you have to climb on it and crawl over as you can't bring ladders close enough to it. I don't think it would take my weight and I don't want to even attempt it.
I'm not sure what to do. It's one tiny bit of the job but an absolute necessity. I don't know whether to just quit, quit and explain why or to ask if there's any alternative roles as i can't physically manage this one.
Any advice? WWYD
