Essential Skills

How Essential Skills Profiles can help you!
The essential skills profiles can:
  • Help determine, based on skill sets, which career may best suit a particular individual.
  • Assist job seekers to write a résumé or prepare for a job interview.
  • Help employers to create a job posting.

Employers place a strong emphasis on essential skills in the workplace. Essential skills are used in nearly every occupation, and are seen as 'building blocks' because people build on them to learn all other skills.

Each profile contains a list of example tasks that illustrate how each of the 9 essential skill is generally performed by the majority of workers in an occupation. The estimated complexity levels for each task, between 1 (basic) and 5 (advanced), may vary based on the requirements of the workplace.

In the case of residential service appointments, there may be 10 to 15 service calls in one shift. Planning and organizing must take into account the distance between customer locations and the urgency of specific calls. When working on new construction projects, job task planning and organizing is geared towards fitting smoothly into a schedule that involves other trades coming before and after them. Plumbers work both independently and in co-operation with other tradespeople on job sites. (3)

  • May use project management software for complex equipment installations to schedule lead times and the completion of project milestones. (3)
Additional Information Working with Others

The degree to which plumbers work with others depends on the specific setting in which they work. On construction sites, plumbers must co-ordinate with other trades onsite as there is an order in which the work should be performed and safety is always a concern. For example, during installation they complete the rough in and then return to complete the finishing after other trades (e.g. plasterers, tilesetters) have completed their work. Plumbers frequently work with an apprentice. Plumbers servicing residential clients typically work with others to a lesser extent. They often work alone on small residential jobs.

Continuous Learning

Although the fundamentals of plumbing remain constant, the nature of the plumbing occupation is changing, resulting in a corresponding need for continuous learning. For example, changes to the Canadian Plumbing Code periodically modify procedures for the installation of piping systems. Advances in technology are also having a significant impact on trade procedures. For example, the use of computer-assisted design (CAD) software is required in some jurisdictions. Advances in technology are also changing the design, applications and materials of systems. Technical courses may be offered when new products, procedures and equipment are introduced. Apprentices learn through a combination of classroom training delivered by community colleges and on-the-job training. In unionized environments, they are paired with journeypersons according to ratios defined in collective agreements. Journeyperson upgrading programs are often offered by joint apprenticeship and training committees with a focus on both classroom and hands-on training. An increased emphasis on worker health and safety means that related training is often mandatory for both apprentices and journeypersons. Many plumbers stay current by reading trade magazines.

Impact of Digital Technology

All essential skills are affected by the introduction of technology in the workplace. Plumbers' ability to adapt to new technologies is strongly related to their skill levels across the essential skills, including reading, writing, thinking and communication skills. Technologies are transforming the ways in which workers obtain, process and communicate information, and the types of skills needed to perform in their jobs. In particular, the use of technology, such as computer-assisted design (CAD) software for system design, layout and project management, is increasing. Self-employed plumbers may also require a broad range of computer skills to operate software applications that help them bill and communicate with customers, track costs and revenues and produce financial summaries. Digital technologies also provide workers with tools, such as cellular telephones, which increase opportunities for verbal interaction and improve workplace safety. For example, workers working independently in remote locations can access customers, supervisors and medical assistance using their cell phones.

Technology in the workplace further affects the complexity of tasks related to the essential skills required for this occupation. For example, sophisticated plumbing installations have increased the complexity of schematics and other diagrams. In contrast, electronic databases, CD-ROMs and keyword search functions make it easier to find information, such as diagrams specifications. Not only can workers complete documents (e.g. work orders) with speed and accuracy using specialized software applications that input data automatically, but they can also calculate costs, material requirements, conversions, electrical resistance, volumes, rates and offsets using Web-based applications, specialized plumbing software and hand-held devices, such as personal digital assistants (PDAs).

Apprenticeship Grants

There are two types of Apprenticeship Grants available from the Government of Canada:
  • The Apprenticeship Incentive Grant (AIG) is a taxable cash grant of $1,000 per year, up to a maximum of $2,000 per person. This grant helps registered apprentices in designated Red Seal trades get started.
  • The Apprenticeship Completion Grant (ACG) is a taxable cash grant of $2,000. This grant helps registered apprentices who have completed their training become certified journeypersons in designated Red Seal trades.
