Okay, let's try it a different way. The bar OmniPlan draws on the Gantt chart goes from the start of the task to the end of the task, regardless of what is between them. Weekends, holidays, days off, it doesn't matter. If you have assigned an 8 hour task to someone who works 2 hours per day, the bar is probably going to span at least 4 days on the Gantt chart. Similarly, if you assign that 8 hour task to someone who works 9-3 on Monday and 9-noon on Thursday, it is always going to cover at least 4 days, because it will span either Thursday to Monday or Monday to Thursday unless it has to go into an additional week (because it couldn't start until 2 PM on Monday, for example, in which case it would occupy 1 hour Monday, 3 hours on Thursday, and the 1st 4 hours of the next Monday, thus spanning no fewer than 8 days). OmniPlan does not draw a chain of sausage links only on the days the resource actually works.

Suppose you worked for your town government as an OmniPlan consultant 2 hours on each Monday and Wednesday. Suppose also that to save costs your town government switched from working 9-5 M-F (5 x 8 hour days) to 8-6 M-Th (4 x 10 hour days). The value you would enter in the town's OmniPlan documents for project hours per day would change from 8 to 10, but a Gantt chart showing tasks assigned to you would not change, agreed?

Not really. A 10 h task that starts on Thursday morning would cover Thursday and Friday before, and only Thursday only after the change, as it fits now into 1 day, therefore the Gantt chart should change here.
