I don't think that people don't like doing those jobs. I believe that it comes back to the toil aspect, since those jobs are undervalued the pay is low and the hours are long. The two solutions I see are:

1. People who would enjoy that kind of work, but don't want to work the grueling hours will do it.

2. For things like harvesting, there was already a good (If inhumane) option, Serfs. You only need o harvest a couple times a year, so if you're on UBI then a couple times a year everyone goes and harvests the fields.
