Coal company owned housing ran the gamut from well maintained bungalows to little more than tarpaper covered shacks.  These 1935-1946 photos demonstrate the varying quality of the company housing provided for miners and their families.

Hills, hollows,  and a lack of improved roads meant isolation for the mines and coal patch towns of Kentucky well into the 20th century.  For those miners not living in company housing, getting to work could mean walking miles to the mine where they worked and then home again after a long day of physically exhausting work underground. Early on the rivers, and later the railroads, were the main means of travel between towns, other than by horse or walking, until the mid-twentieth century when improved roads became common.

Not only were the wages for coal miners low, the wages could also be irregular. In times of decreased demand, or when stockpiled coal exceeded immediate demand, coal companies cut the number of days the miners worked. Three, two or even one day of work per week was not unheard of in these periods of decreased demand, especially during the hard times of the 1930s. The miners in this photo are reading the notice of  NO WORK TOMORROW, an all too often occurrence. When this occurred, the miners and their families still had to eat and pay for housing so they went into debt to the company against future wages.
