What's your biggest headache at work? Technology or people?

people who are ignorant about technology (I work for a company that does mostly IT work so there is no reason the basics shouldn't be understood).

People who are ignorant and know it are not a problem. It's people who know enough to make them think they know it all that are the pain.

Specifically people who think they can manager technology because they have an MBA, despite the fact that they require a wireless mouse. (Because if the little wire comes out they cannot figure out where it goes and why it stopped working!)

Customers. From time to time I have to repair computers for customers and some are that ignorant that one wonders how they even find the power switch.

Incompetent people on managerial positions who make decisions regarding things they have no clue about.

I agree. Most of the companies I've worked for have those types of managers, who don't know anything.

People who snatch credit of other people's work.
People who back bite about their peers to the boss.

+1000 or so.

A writer in a computer mag here in the UK uses the term "custards" for certain customers, it being a combination of customer and another word, which I find quite amusing.

I would suspect that, for most persons, the answer would be people.

Broken technology can be fixed.

LOL!

That's why they're qualified to work as managers, seriously...

As they don't know anything, they spent their time putting pressure on workers

While I have had some mangers that were SERIOUSLY (even proudly) non-technical that were MAJOR headaches, I have also had some that were golden. Good managers are worth more than a rack of new servers, technical or not! Bad ones who can be managed are not a headache, just part of the job. Only the ones who think that they know enough to manage technology without actually understanding it, and refuse to LISTEN qualify for the "<insert your thought here>" award. The ones that also micromanage deserve that award with the oak-leaf cluster!

Luckily the REALLY bad ones are rare. Unluckily, every company seems to attract or build one sooner or later.

Technology - namely anything Microshaft...

And people -

When the aforementioned technology and people are united, what you get is the mother of all headaches.

Ha! I like Custards. Will start using that one I think!
