Leadership Behavioural & Behavioural Communication To be a successful communicator, you should consider this process before delivering your message. § Be clear / confident about what and why you want to communicate. - Information must be useful and accurate. Source Message § Transferring the message into a form that can be sent and correctly decoded at the other end. Encoding § Your success depends partly on your ability to convey information clearly and Feedback Message Channel simply, but also on your ability to anticipate and eliminate sources of confusion. § Methods include verbal / written channels Message Decoding § If the decoder doesn't have enough knowledge to understand the message it Message Receiver can create confusion. § Each individual enters into the communication process with ideas and feelings that will undoubtedly influence their understanding of the message, and their response. 24
Leadership Behavioural & Behavioural Communication – Mental Models Summary of Interview results Research results revealed that, in aggregate, interviewees tended to believe: • The most important thing that can be done to reduce NIHL is through the wearing of HPD; • Rock drills are the biggest source of noise; • There is a need for an engineering or engineered control; • New controls / leading practices may lead to production loss and high costs; • Reduction in NIHL is strongly correlated with enforcement on the wearing of HPD; • Involving people (most affected by adoption of technology or leading practice) in introducing new technology will help overcome presumed inherent resistance to change; • Leadership is vital during change; • Training was seen as the most important behavioural communication element; and • Leaders should coach, demonstrate, show statistics and lead by example. 25

B(A) 28
Training Requirements – Training Centre To Date: § Train all Training Centre Instructors / Assessors. § Use the Training material provided from MOSH, MHSC. § Train all employees when doing Annual Induction Training. Way Forward: § Ensure that all employees are trained by December 2011. 29
Monitoring Program – Implementation progress To Date: § 220 employees trained and assessed. § 220 employees re-assessed. Way Forward: § Follow up assessment of employees after 3 months in the work place. §Continue with HPD compliance in the workplace when routine workplaces are inspected. 30
Manage Roll Out – Problems encounted § Resistance to change § Time taken to take moulds, (6 min) § Contractor turn over § People scared to use PHPD’s in case of losing it § People afraid to report loss, to avoid Disciplinary Action 31
Manage Roll Out – Lesson learned § Have a realistic rollout schedule § Dedicated resources to assist with parading employees § Employee awareness to Hearing Loss § Actual observations to Induction Trainees § Buy-in from line supervision § Safety and Productivity. 32
Manage Roll Out – The Way Forward § Ensure all at risk employees are issued with PHPD’s § Continue with Training Awareness with audio visual training 33
Conclusion “TO HEAR OR NOT TO HEAR” ? The MOSH Leading Practice Adoption Process is the Tool to successfully implement this Leading Practice or any other Leading Practice. 34
