make personal phone calls
ask for donations/sponsors to a charity
use the bathroom (#2, LOL)
eat smelly foods

I have to agree with asking for money (donation, school sales, etc).

I'll add, eating at your desk.

Working less and talking more.

Take office supplies home.

I totally agree with those selling school fund raising stuff. I use to just dread when this one person would come over from the office next door to sell stuff for her daughter's school fund raiser.

check your email

play music!!!!!!!!!! :(

Add my name to the "school, scouts fundraiser" list!

chew gum

bring potpourri

wear too much perfume

Shop online or otherwise trawl the 'net for personal use (but I'm my own boss and if I want to procrastinate by browsing GW it's nobody's business but mine. :) )

=OR=

Reading the question a different way....

Dodge into the supply room for a quickie.

gossip (although some studies suggest that there is "good" gossip)

drink at lunch

Ditto with fundraisers

Sell Girl Scout Cookies.

Sell raffle tickets.

Play games on your computer.

Come to work sick. I used to hate when people came to work sick. It just gets everyone else sick too!!!

Gossip

Always come in late

Cook smelly food for lunch

cook popcorn in the microwave

discuss salary

floss your teeth

Personal grooming- i.e. brushing or combing hair, messing with your nails, flossing

Wear cologne or perfume.

oh, yeah -- I think lukkiirish has it with "come to work sick"! I worked with a complete JERK (would like to call him worse) who actually brought his TWO SICK KIDS to work because he couldn't send them to school!!!

Right or wrong, come to work sick…..very good answer!

party_music50 ... Oh I am not sure what I would do if I worked in an office where sick kids were allowed. That's a tough one for a sympathetic manager also.

I agree with the previous post about asking for money for whatever reason. But what bugs me is when people call in "sick" and then everyone else has to make up their work at the expense of their own work. ( my work gives us paid sick days they get ABUSED and one day its is gonna get revoked because of this)
