16.4 Communicating Effectively: Methods, Accessibility & Conflict

Key Takeaways

  • Oral communication is fast but leaves no record, so important instructions such as variations should be confirmed in writing by email or letter.

  • Adapt your communication: face people with hearing loss and speak clearly, describe hazards to people with visual impairment, use plain language and check understanding for learning difficulties, and avoid jargon and use visual aids for language differences.

  • To handle conflict, stay calm, listen, establish the facts, agree a solution within your authority or refer it to your supervisor, and record the outcome.

  • Poor communication causes mistakes, accidents, delays and extra cost between workers and managers, and complaints, lost business and damaged reputation with customers.

16.4 Communicating Effectively: Methods, Accessibility & Conflict

Unit 210 learning outcome 3 (6 of the 20 test questions) asks you to choose suitable communication methods, communicate effectively with people who have particular needs, deal with conflict, and explain the effects of poor communication.


Choosing a Communication Method

MethodAdvantagesDisadvantagesBest used for
Face-to-face (oral)Immediate; questions answered on the spot; body language helps understandingNo record unless written up; easily misrememberedBriefings, toolbox talks, quick queries, customer care
Telephone or radio (oral)Fast over a distanceNo record; noise on site; no visual informationUrgent messages and coordinating deliveries
Email (written)Fast; provides a written, dated record; can attach drawings and photos; can go to several peopleMay not be read promptly; tone can be misreadConfirming instructions and sending documents
Fax (written)Sends a copy of a signed document over a phone lineNow largely replaced by email; poor qualityRarely used today, but still listed in the Unit 210 range
Letter (written)Formal record with a signatureSlowFormal notices, contracts and replies to complaints
Drawings, diagrams and signsClear visual information, understood regardless of languageMust be kept up to dateTechnical information and safety warnings

Rule of thumb: anything that changes the work, the price or the programme, such as a variation or an instruction given by phone, should be confirmed in writing.

Communicating well with customers

Good communication is part of customer care. Introduce yourself and show your ID, explain what you are going to do and how long it will take, warn customers before you isolate circuits or make noise and dust, and keep them informed of progress and any problems. Your tone of voice and body language (eye contact, posture, not checking your phone while someone talks to you) matter as much as your words. On the telephone, give your name and company, speak clearly, write down messages accurately (who called, when, the number and what they need) and pass them on promptly.


Communicating with People with Particular Needs

Physical disabilities

  • Hearing impairment: face the person so they can lip-read, speak clearly at a normal pace (do not shout), make sure your face is well lit, and use written notes, text or email. A sign language interpreter may be needed for important discussions.
  • Visual impairment: introduce yourself, explain what you are doing, warn of hazards such as lifted floorboards or trailing leads, put things back where you found them, and offer information in large print or verbally.
  • Mobility impairment: keep routes clear, arrange accessible places to meet, and talk at eye level with a wheelchair user.

Learning difficulties

Use plain language and short sentences, explain one step at a time, use pictures or demonstrations, check understanding by asking the person to tell you what will happen, allow extra time, and involve a carer or family member if the person wishes.

Language differences

  • Dialects and accents: speak clearly, avoid slang and local expressions, and check that you have been understood.
  • Foreign and second language issues: use simple words, avoid technical jargon, use drawings, pictograms and demonstrations, provide translated material where available, and use an interpreter for important matters. On site, make sure every worker has understood safety information and inductions, not just signed for them.

Dealing with Conflict

Dealing with Conflict

The Unit 210 range lists conflict between customers and operatives, between co-workers, and between supervisors and operatives. The approach is the same in each case:

  1. Stay calm and polite; never argue, swear or become physical.
  2. Listen without interrupting, and let the person explain.
  3. Acknowledge the concern and apologise for any inconvenience where appropriate.
  4. Establish the facts rather than taking sides.
  5. Agree a solution if it is within your authority; otherwise refer it to your supervisor or manager.
  6. Record what happened and what was agreed, and follow up.
SituationGood response
A customer is angry that you arrived lateListen, apologise for the inconvenience, explain briefly, agree how the work will now be completed, and tell your supervisor
Two co-workers disagree about who should tidy the work areaTalk it through calmly, refer to the job allocation, and involve the supervisor if it cannot be settled
An operative disagrees with an instruction from a supervisorDiscuss it privately and politely; if it is a safety concern, say so clearly; use the company's grievance procedure if needed

The Effects of Poor Communication

BetweenPossible effects
OperativesMistakes such as wrong cable routes or materials, work done twice, accidents (for example a circuit energised while someone is working on it), friction and low morale
Operatives and managementWrong materials ordered, missed deadlines, programme delays, extra costs, safety rules not followed, low morale and staff leaving
The company and its customersComplaints, disputes, late or non-payment, loss of repeat business and recommendations, damage to the company's reputation and possible legal action

Tip

If a test question asks for the best method to communicate an instruction that changes the work, the answer is usually a written method, because it provides a record.

Test Your Knowledge

Write the instruction on the wall where the points will go
