The part-time casual basis, temporary employee thing is a scam perpetuated by the HR department. In the initial interview they brag of how you have the great opportunity to work for the City of Kingston and how it’s such an honor to be chosen.
What they don't tell you, even if you ask them outright, is the part-time casual a rip. You have no chance of getting a permanent full time job with the city unless you know the right person or are related to someone inside. The HR people will lead you on to think you will get a full time job, even if you tell them you are quitting a full time job to work for them. It’s still the old school boys club where you get hired only if you have a solid inside person, other than that, all you'll ever be is call-in, casual part time help working maybe 24 hours a week.
Pay, easy work
Never going to get a full time job
