How to tell a boss his staff are rubbish?

So help me out.... what wrasse the original title?

Security oufit, like Chub locks?
I realise the OP was herring on the side of caution but were I a staff member,
I'd turn on my my heel and orca out.
I'd obviously be tilapia if he didn't get the job. Of course, you can't char eveybody with the
same brush. I mean, you're codling nobody but yourself. By all means try to minnow out the bad apples
but to do this, you really need a licence to gill. But to do this when beginning to flounder would be oarfish at best.
After all, the staff would think moray of you if you were to ease the tension with an impromptu conger.
Dace facts, you can't loach another man's glory. To do so would be extremely viperfish.

Well if he replaced the carp with virgin sturgeon he'd be fine, after all virgin sturgeon need no urgin' (as all good rugby players know)

Mako what you will of these puns
