Researching the Role of a Postman

I decided to write the protagonist of my script as a village postman. Even though this is a job I have been aware of most of my life, in order to make my script as realistic as possible I have decided to research the role and the specifics. 

According to the National Careers website postmen:

• Earn on average between £20k and £25k a year
• Typically 41 to 43 hours a week
• Has early mornings

Day-to-day tasks include: 

• Sorting out mail into address order
• Operating automated equipment
• Delivering mail on foot, bicycle or van
• Get customer signatures for registered post
• Pick up mail from the post office, post boxes and businesses
• Deal with wrongly addressed mail or returned mail 
• Move mail to and from processing centres

Skills needed include:

• Customer service skills
• To be thorough and pay attention to detail
• The ability to work independently 
• Patience and the ability to remain calm in certain situations 
• The ability to accept criticism and work well under pressure
• The ability to work well with others
• Excellent verbal communication skills
• Knowledge of English language
• To be able to carry out basic tasks on a computer or hand-held device 

From learning this, I want to make sure I incorporate these into my script to make it feel as realistic as possible. 

Ideas to include: 

• A certificate on Ted's wall for his many years as a postman
• Collecting the post from Lizzy's shop/post office, would further the red herring narrative that she is the admirer
