The hours can be long and unpredictable. Not all workers are qualified and it's becoming necessary to oversee and train people who should have been screened better. Not sure what the problem is, but they keep losing job qualified and skilled workers while those who are unqualified or quite frankly freeloaders seem to be staying on. This lopsided turn over in staff isn't a good indicator either, and will only end up slowing down jobs rather than helping in the long run.
