IF Postman Pat were to find himself negotiating the job market of today, it's likely he would need an open mind to a career change.
In today's fast-paced, technology-rich world certain careers are changing drastically, and in some cases becoming obsolete.
The growth of the digital sector has particularly changed the state of job security, taking what were once relevant and reliable occupations out of the hands of humans, and hard-wiring them into computers.
In June, consultancy Deloitte mapped how Australia's key 18 industries would fare at the hands of the "digital disruption juggernaught".
The report singled out six industries, representing one third of the $1.4 trillion Australian economy that were vulnerable to a substantial impact within a short space of time.
The sectors are: finance, retail, media, arts and recreation, real estate and information technology.
This disruption trend combined with slower economic growth has led to a reduction in job opportunities in many industries.
US job search site Career Cast has this week released its own study into the job market, forecasting expected decline in employment opportunities out to 2022.
Its top ten endangered jobs of 2014 are:
Postman: Internet communication has made the use of the postal service somewhat of a novelty for many people, resulting in a profound decline in postal jobs. In Australia, daily mail deliveries may be reduced to a three-day-a-week services later this year. Classified as the most endangered, the postal delivery category finished at the top of Career Cast's list.
Farmer: Advancements in agricultural technology and machinery has meant fewer hands can do more.
Meter reader: Gone are the days of waiting for the meter man. Utility companies can now implement remote-viewable readers, saving a trip to out to customers.
Newspaper reporter: It's not front page news that the digital age has dramatically reshaped newsrooms across the world.
Travel agent: Be it booking trains, planes, automobiles or hotels, the consumer is often happier to surf for the best travel deals they can find and skip the middleman.
Forestry worker: Better technology often means bigger machines, leaving less room for the little guy trained in the felling of trees.
Flight attendant: The airline industry over the last decade has undergone plenty of shocks, and the high-flying crews have not been immune. Long-term hiring projections are not looking good for flight attendants over the next decade.
Drill-press operator: Career Cast listed drill-press operator as one of the least stressful jobs in 2013, but these manufacturing jobs will be much harder to find by 2022.
Printing worker: As the world becomes more digital first there is less need for hard copy printing.
Tax examiners: Technology has reshaped the role of the tax office, meaning fewer hands are needed on deck. The Australian Tax Office, for instance, is expected to shed more than 2300 full-time jobs in 2014-15 as a result of budget cuts.
