Isn't vermicomposting a lot of work?

From WormWiki

Once your bin is built or purchased, vermicomposting takes very little time. In fact, the worms seem to do better if left alone, just so long as their environment is dark, moist, and has enough food and air. Setting up the bin to begin with will take a few hours at most. (It's faster if you have a paper shredder!) Then you can choose to feed your herd anywhere from daily to weekly. Though in the beginning you should probably check the bin every 2-3 days to make sure you aren't getting anaerobic pockets or too much water, as time goes on, it can take as little as a half an hour a week to maintain the worm bin.

Since worms eat the microbes on the food, and not the food itself, it's a good idea to set your bin up a week or so before your worms arrive, to make sure the environment is one they will want to stay in.

In the beginning worms often try to escape the unfamiliar environment. Check the drip pan regularly. A way to avoid worms drowning is put a little shredded newspaper in the drip pan to allow the worms to avoid standing water. Again, once you and they are more comfortable, you can decrease your 'chores' to about a half an hour a week.

Harvesting the vermicompost can be done in either a labor intensive way or not. If you choose less labor intensive ways to harvest, you may have to set things up and then wait a few days to weeks, but you don't have to do anything in the mean time.
