RedKetchup's Forest Center: What do the workers do? Are they needed?

[LadieWinter]

I have just recently discovered the Forest Center under RedKetchups list of mods. It seemed pretty cool so I decided to try it out.




I'm a bit confused about the "workers" that you can employ there. I have already built the herbalist building. It stills employ a herbalist and not a "worker". I tried searching around for information, but I can't seem to find any information on the center itself, much less about the workers.




Are they important? What do they do exactly? From what I can tell the herbalist functions just fine without any "workers" employed. If there is a link to any more information about the center, please feel free to share. : )
