We had five people come and go within a month (sometimes within less than a workday) during the last one and a half years. Good workers are hard to find, specially in the fireworks/disposal biz. They come here and keep babbling about how they would love fireworks and be a part of a pyro company, then the first truckload of boxes from our suppliers comes in and you can clearly see the "that's not what I expected" look on their faces. Yeah, we also do interesting and cool stuff but most of the time it's heavy work, lugging stuff around, manufacturing shells for days after days until your fingers literally start to bleed, poisonous chemicals, metal and coal powders that let you look like a coal miner in less than five minutes, and there always is the risk of getting blown to pieces.
Sure, it's not everyone's pint of beer but in general, it's not the risk or dirt but the physical labour that puts them off. Kids today just don't wanna do hard work anymore, even for something they allegedly love.
