Our suspicions have been confirmed: 2:55 p.m. is the least productive time of day for office work. A recent survey questioned more than 400 workers and noted 2:55 as the time when workers start zoning out on the Internet or planning their evenings. 

Conversely, 10:26 a.m. was cited as the most productive time, followed shortly by 4:16 p.m., which is when people are motivated by a desire to finish on time. 

**FYI: Most workers said they began to mentally switch off an average of 18 minutes before the end of the day.
