This is because of the amount of training firefighters need. Volunteers have a hard time remaining qualified because of the time and expense involved in training. Much of the growth in paid positions will occur in small towns where volunteers used to do the fire fighting. Small towns that are growing may need more firefighters. Little growth is expected in city departments.
Layoffs are rare because fire protection is a required service.
In addition, the rate of turnover in this occupation is low. However, most job openings will be to replace people who retire or leave the occupation. Many people are attracted to this occupation because of the relatively high pay and low education requirements. Others are interested in fire fighting because of the excitement and challenge. Competition for these openings will be strong.
