Would you tell the boss his fly was down?

The workplace is full of awkward conversations. Which ones are you most reluctant to have?
Employees are more comfortable telling co-workers that their zipper is undone than to point out any other embarrassing gaffes, according to a recent CareerBuilder survey. Two-thirds of employees said they’d tell a peer about an undone fly, while half would do the same to a higher-level co-worker.
Lowest on the comfort scale? Discussing personal hygiene. Just 28% would tell co-workers they needed a shower. The number’s just 11% when the dirty employee is higher in the ranks.
The rest of the list:

1. You have food in your teeth (66% for a same-level co-worker, 49% for someone higher)
2. You have something in your nose (51% and 33% )
3. You have a stain on your clothes (51% and 34%)
4. Your hair is messy (33% and 13%)
5. You need a breath mint (33% and 14%)
6. Your clothes aren’t appropriate for the workplace (32% and 10%)
