Working for Mueller has good and bad. It is good in the sense that you can basically make your own schedule. You are assigned work, and have a set amount of time to complete it. They are also willing to give you more work and send you to various areas to help where they need it.
Mueller has downfalls though, and I wish I could only say one or two things. You are using your own vehicle and driving to many locations, putting many miles on your car. The way gas pay is reimbursed, is basically you're not taxed 50 cents for every mile you drive, so you're not really getting paid for this, you're just not getting taxed on it and this would have been a tax writeoff anyway. Also, the communication can be poor. You only talk to one person, your manager, You have no co-worker relations, it's a very independant job. There is also very little room for advancement and they hand out a raise about as often as a bank teller gives you too much money. I worked there for over 3 years and did not recieve one pay increase. It was not until I told them I wasn't interested in working for them anymore, that they mentioned a raise to me.
All in all, it is a simple job. You travel to houses, farms and commercial buildings and measure and photograph them, and then punch data into the computer. It is a good part time job if you need a little extra cash, such as the situation I was in and was back in college. You are also outdoors, which obviously has its good and bad. The hardest part of the job for me, was in winter times, drudging through deep snow to obtain the pictures they desired. You can make a decent hourly wage if you don't have to travel too far to the locations and plan your route properly. But keep in mind you are putting wear and tear on your car.
