when there's no point to go on ......

This is not a suicide note. This is frustration over work.
Apparently when the company decided to hire a person with no work experience to supervise
production, they have gone bonkers.
This new fella (6mths) slacks in every sense of the word. He lacks focus, has an attention span of a 3 yr old toddler, and behaves like a teenage brat. Even the operators are sick of his irresponsible behaviour.
Just as we are reminded everyday to not forget about safety, this idiot behaves as if he was never at the fire incident. This afternoon, when the solvent alarm went off (level 1), he pretended as if nothing happened (he was in the sheeting process). I had to step in and announce to the mixing boys to check & feedback. Within 1 min, the 2nd level alarm went off, and by this time everyone had to stop their work and listen for evacuation message. The idiot fella didn't even appear at the control room window. Luckily foreman Z was around. He went upstairs to check, and managed to contain the situation. No fire, just high level of solvent. But then there was some damage and leakage on the pipes, causing some cleanup required.
And still the idiot fella did not appear.

Finally after 10mins of fruitless waiting, I called him to the control room.
This was his reply,
He heard the alarm & announcements, but because of the paper work he was clearing
he did not feel the urgency to attend to the alarm.
He feels the urgency is for him to clear the paper work (which was due since morning but obviously delayed), cos the boss was expecting him to submit by the end of the day.

I felt sick to the stomach hearing this reply. Shit! I care more for this process than my own line, and here this fella gives me such reply.

So I told this straight to his face:
YOUR paperwork is more urgent than the explosion that might have happened???!!!
So it's ok to let the bldg explode as long as you clear your "URGENT" paper work???!

Some people have the nerve coming in to work, and yet do nothing and still get paid for it.
I have tried my best for the last 2 weeks to guide this fella so that he could pick up his work. Instead, I end up doing his work, and now leading his line for him? What is happening here?

I GIVE UP!
First thing tomorrow morning I will throw in the towel, and stop guiding him whatsoever.
It is about time that he swim or sink without me.
