Losing your job is just as much as a disaster, if not more, than an earthquake or flood.  We all need money.  When there is not enough of it, we have problems.

Mini preppers have the advantage of having many of the items that they need already stored in their homes.  This preparation can supplement other emergency sources of incomes, such as unemployment insurance.

Everyone should try and have an emergency fund of money that they can live on for at least 6-9 months.  Obviously if you lose your job you will cut everything but non-essential items, so it doesn't have to be the amount of money you currently spend each month.

Most people can cut their expenses and save more money if they are a little more frugal.  See Frugal Happy Families and other similar sites for money saving ideas. Save a little money each month, and start building your emergency fund.  

Should you lose your job, you will also find help with job resumes, interviews, etc. on Frugal Happy Families.

If you have stored the food that you normally eat, life will seem a lot more pleasant while you are looking for new employment.   Having the food and other basic commodities you need for your family will remove one layer of concern during what is for most people a very stressful time.

I know many a family that survived a job loss by eating their food storage, and using other stored supplies like personal hygiene items.  When you store items you use on a regular basis, there is never any waste. 

Storing and saving money and commodities in times of plenty is just smart.  Strength your homes and families and feel more secure.  Hope for the best, but prepare for the worst.
