Govstooge v the CPSU

My HEO approached me today with yet another stupid question:

HEO: Govstooge, why haven't you conducted interim PMDS reviews with your staff this summer?

Govstooge: I can't. All my staff are members of the CPSU.

HEO: So?

Govstooge: The CPSU have an embargo on PMDS since March or so of this year?

HEO: So?

Govstooge: (Jesus!) Look, if I was to ask them to fill out their self-assessment forms, I would be asking them to contravene their union's advice.

HEO: So?

Govstooge: Look, knucklehead, what I earn isn't enough to enable me to take on several hundred COs and their union officials - officials, might I add, who generally earn twice what I do.

So as far as I'm concerned PMDS is not happening this year. Haven't you heard?

HEO: No.

Govstooge: Well, maybe if you didn't have such a fetish for listening to Gerry Ryan every morning talking about his holidays and the latest Danish pastry he's shoving down his gob, you might have heard. Actually, now that I seem to know more than you do, can I have your salary?

HEO: No.

HEOs. What are they good for exactly?
