Robots (really machines in general) are good for repeatable tasks with low variation, but a lot of those are already covered by machines. The benefit of people is that they're incredibly adaptable for the price you pay them (or even if you paid three times as much as what you do now).

To use one example, you can't make a robotic janitor. You can retool your system so that trash collection is automated (like having a garbage chute or whatever) but it's always going to be less expensive to pay someone to pick up the trash.
