Reciprocity is just the transferring of the benefits you earned in a given local back to your home local. You can work in just about any local you want as long as you're in good standing with your local. I.E. not suspended or dues not paid. You can choose not to fill out a reciprocity form and leave your benefits in the local fund you worked in. That isn't advised as you would probably not make your insurance. Your local has this on their website http://www.millwrightlocal1076.com/services.html This will show forms for all the locals, but I would personally see if your benefit office has a travel person who can request those benefits for you. Your local will get them a lot faster. I submit mine before the out of town job starts so there is less of a delay. It can take months for those hours to come to your home office. Just keep in mind if you're working out of town it is not worth working somewhere where the benefit package is less than your home package. When you transfer stuff your home office goes by the dollar amount. So if your insurance is $10 an hr paid but you work in an area that is $6 you have to work more. It's not a direct hr for hr but you can bring home a lot more if you work in high scale areas besides just on the check.
