Reading between the lines: my job is fairly secure, but everyone will hate me and I won't get holidays for the next 6 years.
You're reading too much between the lines. Your job is secure if you can actually do the job........don't fcuk up and you'll keep it.
Hate you? WTF?

There is no hate in the rank and file.
And you
WONT get the holidays you are entitled to every year. If you are hoping to get school hols, christmas, easter, spring carnival off, better start looking for another job.

What happened at the training college would have had any manager who presided over it in the senate explaining their actions.............maybe that will happen?
