Sorry to make you deal with this rambling post. There is a point below, somewhere.
The limit to this type of commuting will be reached when it starts to make more sense to rent a place close to work.
Camden Alabama Real Estate
You can buy this delightful mobile home (tornado bait) near Camden for $49K, close to the boat ramp, 3 bedroom 2 bath, for about $290 per month, with an 8% loan, probably all that a hillbilly with bad credit can get.
Camden AL
The median gross rent in Camden is $280 per month, so that is one week's pay for a $7 per hour plant worker.
Selma Classifieds
$280 per month is $14 per day, so when the cost to commute is higher than that, it will start to make sense to move. At the current cost of gas, that is about 3.83 gallons worth, which might mean that at about 50 miles away from the plant, it is roughly breakeven, depending on the efficiency of your car.
Here is the budget for a plant worker making $7 per hour, living 50 miles away from the plant:
$this->bbcode_second_pass_code('', 'Gross pay/mo 1120
Net pay after tax 952
gas 280
rent 280
food 180 ($6 per day, eating cheap)
utils 50
other 100
Total living expenses 890
Disposable income 62')
So, it's looking bad, particularly if you are a single mom with kids, paying a babysitter, or have a lot of other expenses that you have to deal with.
You will have to quit smoking, for sure. $2 per day is not enough for a pack of cigs, which I think is about $4 right now.
Also, this assumes that you do not have to pay any co-payment or contribution for medical insurance, which most everyone has to do at this point.
The most sense would be for you and two work buddies to share this 3-bedroom trailer close to the plant. Less commute (maybe carpool) only 1/3 of the rent and utilities. Some of the local immigrants in my area use this strategy, sleeping 10 per house, etc. to get cheap on rent.
I guess what this all boils down to is: someone is going to have to change. Either change how you live, change the car you drive, or some combination, in order to work at this plant.
