Bus driving itself, is an important job that is required to be done to make the community have with continual bus time tabled services. I suppose that one thing I am pleased is that Bus Operators are able to ensure there are bus drivers fulfilling time tables. That in itself may be difficult. Yet when you speak to bus drivers - some could be overqualified and others will be quite satisfied to even have a paid job and there will the the rest that are using the job as a landing pad to other jobs in other industries.
Take my father (rest his soul), he came to the country as a professional tailor, yet he couldn't get a professional job in Australia as well as a professional tailor. He was also a truck driver in the NSW timber industry and work fixing roads with gangs of men! Then the Conductor job on a tram got his his career job as a bus driver and then Bus Inspector Third Class. I really respect his jobs and how he got to retirement - he was well respected at Waverley Bus Depot! Sorry got carried away!
So I think Bus Operators have to look at ways of keeping their workers and keeping them happy , so they provide good long service and this will not affect bus time tables in a negative way!
