My J.O.B

Let me start with a -ve word. My job SUCKS. Enough said?

In the 1st year of this JOB, you have to follow your [s.c.m.p] time.
In the 2nd year of this JOB, you still have to follow your [s.c.m.p] time.
In the 3rd-5th year of this JOB, you have to follow your [c.m.p] time.
In the 6th year (if you ever stay so long), you have to follow your [c.p] time.
The [c.p] time will always follow you from the 6th year onwards until you have the opportunity to step & become [p].
Even when you r [p], you still have to follow [c] time.

The your unlucky [WAG] have to follow your time!

So why do you still do this JOB?
Why don't you go & become [c] instead?
I have no IDEA.
