Job Task Planning and Organizing
  • Contractors and supervisors of mechanic trades establish their own work schedules and shift priorities and appointments to accommodate emergencies and cancellations. They often determine how best to organize their work to meet deliverables and timelines of team-based projects while supervising multiple job assignments. They use their judgment and experience to coordinate and integrate job tasks with other workers and to decide job priorities. Contractors and supervisors of mechanic trades must frequently rearrange their schedules to meet clients' requests, deal with faults and mechanical failures and may participate in impromptu meetings in the midst of their daily routines. Because their tasks may vary greatly in both the types of tasks they face and the order they complete them they must prioritize tasks to maintain efficiency. (3)

Decision Making
  • Choose supplies, tools, and parts needed to complete installation, maintenance and repair jobs. For example, a heating, ventilation and air conditioning contractor selects ducting sizes and hanger types to complete a small forced-air furnace installation. (2)
  • Choose training topics and methods for workers you supervise and employ. Review their performance over time and match their experience with relevant training opportunities. (2)
  • Determine job assignments according to workers' technical skills and preferences. (2)
  • Choose sanctions and rewards to discipline and motivate workers you supervise. In some cases, reprimand employees who consistently miss work or production targets and praise those who always meet production or service goals. For example, a heating systems contractor gives pay increases to workers who consistently complete repairs and installations without faults or delays. (3)
Back to Top

Problem Solving
  • Workers cannot immediately complete repairs, services or installations due to inclement weather, lack of required parts and equipment breakdowns. Inform clients about potential delays and arrange to pay additional fees to cover express shipping costs. For example, a boat engine repair foreperson communicates directly with suppliers to locate specialized engine parts and expedite special orders before explaining delays to customers. (2)
  • Conflicts among crew members are slowing work. Separate workers to ensure safety and to restore productivity. Meet privately with the individuals later on to explore the roots of conflicts, discuss work options and resolve differences. (2)
  • Deal with mechanical faults that are uncommon and have not been documented in service manuals, bulletins, recall notices or other manufacturers' information. Call manufacturers' hotlines or service technicians to relay the nature of the faults and seek their advice. For example, air conditioning and refrigeration contractors call manufacturers' service hotlines when their workers cannot completely repair new air exchange systems. (3)
  • Deal with customers who cannot pay or are unhappy with the quality, price or timeliness of jobs. Visually inspect the work, review cost estimates and present clear documentation of work carried out. Diplomatically describe the tasks undertaken to complete the jobs, provide cost breakdowns of parts and labour charges and may negotiate cost reductions to satisfy customers. In some cases, call collections agencies to secure payments if customers are unable or unwilling to pay for jobs. (3)
  • Workers are disgruntled and voice complaints about work conditions. Attempt to resolve workers' concerns by speaking with them directly, demonstrating empathy and avoid making false promises to cater to unreasonable demands. Clarify issues and then engage workers to identify possible solutions. Supervisors may pass concerns on to management and business owners. (3)
  • Crews are not completing reporting forms correctly. Speak directly to workers and organize meetings to review data recording and reporting procedures. In some cases, point out the negative effects of incomplete information such as compromising quality control and historical data. Monitor workers' reporting on documents and provide additional feedback to ensure the information is correct. (3)
Back to Top

Finding Information
  • Find information about the legal requirements and standards for the jobs you carry out. For example, an aircraft maintenance supervisor refers to the Airworthiness Directives handbook published by Transport Canada to locate information about safety and regulatory requirements for aircraft being inspected or repaired. A heating systems installation contractor refers to the provincial Environmental Protection Act to determine the oil tank replacement periods of fuel storage tanks. (2)
  • Find technical data and specifications of tools, equipment and materials. Read service and repair manuals, review job histories and talk to senior mechanics and other experts. (3)
Back to Top

Critical Thinking
  • Evaluate training needs of the workers. Consider current business trends and skill shortages within the organization and examine licensing or regulatory requirements for training. For example, supervisors of automotive mechanics assess the need to train their mechanics in gasoline-electric hybrid engine service and repair. (2)
  • Judge the condition of mechanical parts and systems. Data may be synthesized from diagnostic tests and compare it to information in service manuals and manufacturers' bulletins. For example, a supervisor of aircraft maintenance technicians evaluates the condition of landing gear systems by testing and inspecting struts, tires, wheels and brakes. A refrigeration contractor may evaluate the working condition of a walk-in cooler by checking and testing the thermostat, looking for sources of heat inside and near the cooler and by verifying and testing the integrity of the insulation. (3)
  • Evaluate the quality of work of various installation, maintenance and repair work completed by the workers. Closely inspect the work, take measurements and analyze production data. Measurements and operating data may be compared to manufacturers' specifications and legislated standards. For example, a heating systems contractor inspects the installation of a large wood burning furnace to ensure it meets the National Fire Code of Canada specifications. An aircraft servicing leader inspects scheduled maintenance work to ensure it meets quality guidelines in Transport Canada's Airworthiness Manual. (3)
