Physical Demands: Heavy physical effort is required in constantly climbing in and out of different machines, pushing and pulling levers continuously while machine is in operation, and lifting such items as opening and closing tail gates on dump trucks. Work is strenuous because of the large equipment operated, the frequent adjustments made, and the adverse operating conditions. Considerable strain is caused by the constant vibration of the equipment and the jerking and jolting from operating over rough surfaces. Frequently lifts and carries items weighing up to 50 pounds and often puts forth similar effort when pushing, pulling, turning and positioning parts, assemblies, equipment and tools.

Working Conditions: Operation of large and complicated equipment in difficult circumstances increases exposure and risk of injury. Works both inside and outside and is exposed to hot and humid weather and/or extremely cold weather. Ice, road oils, and other items such as loose gravel and rocks create hazardous conditions. The operator is subjected to noise, vibration, dust, dirt, oils, solvents, and fumes from motors and exhausts. When working inside, must ensure proper ventilation to minimize fumes while welding and/or other fumes caused by equipment or vehicles. Worker is frequently exposed to the possibility of receiving cuts, abrasions, bruises and strains while servicing and operating equipment. Follows prescribed safety practices and uses safety equipment such as protective hearing devices and hard hats.

Continued Condition of Employment For Probationary Period: As a condition of employment for accepting this position, you will be required to serve a 1-year probationary period during which your fitness and whether your continued employment advances the public interest will be evaluated. This probationary period is an extension of the appointment process and therefore requires the agency to determine if continued employment would advance the public interest, meet the organization goals and mission of the agency, and/or otherwise promote the efficiency of the service. In determining if your employment advances the public interest, the agency will consider:

  • your performance and conduct;
  • the needs and interests of the agency;
  • whether your continued employment would advance organizational goals of the agency or the Government; and
  • whether your continued employment would advance the efficiency of the Federal service.


Under applicable law, the employment of an individual serving a probationary or trial period automatically terminates when that period ends unless the agency affirmatively certifies, in writing, that the individual's employment should continue and that their appointment should be finalized. In the absence of agency action to affirmatively certify continued employment beyond the probationary or trial period, such appointments are terminated. Upon completion of your probationary period your employment will be terminated unless you receive certification, in writing, that your continued employment advances the public interest.
