Employment of stationary engineers and boiler operators is expected to show little or no growth through the year 2012. Continuing commercial and industrial development will increase the amount of equipment to be operated and maintained. However, automated systems and computerized controls are making newly installed equipment more efficient, thus reducing the number of jobs needed for its operation. Furthermore, relatively few job openings will arise from the need to replace experienced workers who transfer to other occupations or leave the labor force. The low replacement rate in this occupation reflects its high wages.
