It really depends on the company you work for and what the needs are. As a union carpenter, I spend most of my day building things. I do many things from wood and metal framing to finish work such as trim work and installing cabinets and countertops. The great thing about being union is good pay and benefits that travel with you from company to company. It is heavy work and you can't be afraid to get your hands dirty, but it is really cool building stuff and you get a great sense of pride from what you do. You do have to have tough skin for any job in the construction industry. I have seen the culture lighten up slightly over the years, especially with more harassment laws in place, but it can still be harsh. The trick is learning how to handle it and not take it personally. If you can do that, you will find a lot of satisfaction in working with your hands.
There's a lot of sweeping, untangling cords, and carrying material. Carpenters are typically haggard people trying to get paid. Arragonce can be a serious problem. Incorrect building can be dangerous and calling out the guy who's about to do it can lead to a fist fight. It very fun though and the finished product will feel like a thing of beauty.
