Serious question!

This is an easy-going place to work most of the time and most of the people here don't give a rubbery fuck what I'm up to provided my work is completed. Which it always is and, if I do say so myself, to a very high standard.

But there are three miserable hags behind me who insist on reporting every 9.02am arrival, every 1 hour and 30 second lunchbreak and every single use of the internet to their equally miserable and haggish manager. This manager then sends this info to my manager, who couldn't really give a plasticy shit about any of it, but who has to act on it.

So, can I slaughter them on the grounds that each one of them is a joyless flesh-waste?
