Pointless emails, smelly lunches and stealing your favourite mug.

These are some of the habits which annoy us the most about our co-workers.

A recent survey revealed the things that make us want to scream into a pillow when it comes to the people we work with every day.

Others include, people stealing your lunch out of the fridge, nosy co-workers reading your emails over your shoulder, eating smelly lunches at their desk, describing their dreams and moaning about their personal life.

Some more crimes include stealing your favourite mug or pen, leaving empty wrappers in tins of sweets or not refilling the stapler

And it doesn’t end there, as colleagues who dash out of the door at 5pm on the dot also drive us nuts.

The survey of 2,000 workers was carried out by animal welfare charity The Brooke, to mark World Donkey Week.

A spokesman said, “We can all relate to the grumbles in this list.”

But these aren’t called “first-world” problems for nothing.

“Our research brings home the fact that no matter how annoying our work life can be, it doesn’t compare with the hardship suffered by working animals around the world today,” he added.

This may be something to bear in mind the next time your co-worker munches on a packet of pickled onion crisps when you’re hungover.
