Enterprise workers say wasteful meetings and excessive emails are the top productivity killers at their jobs, according to recent research from Workfront.

The report was based on data from a survey conducted in June 2017 among 2,001 US respondents, all of whom are employed by a company with at least 500 employees and who are "knowledge workers" (they work primarily on a computer and collaborate with other people on projects).

Some 57% of respondents say wasteful meetings get in the way of their work, and 53% say excessive emails get in the way of their work.

Respondents say they spend just 44% of their workweek performing the primary duties of their jobs, on average.

The rest of the time is split between emails (15%, on average), administrative tasks (11%), useful meetings (10%), nonessential tasks (8%), wasteful meetings (8%), and everything else (4%).

Respondents say the biggest email mistakes in the workplace are using lengthy messages to relay information that should be conveyed face-to-face, and being forced to follow lengthy email threads.

Respondents say the most overused buzzwords/phrases at their workplaces are "think outside the box," "synergy," "bandwidth," and "circle back."

Workers give their own productivity an average score of 8.4 on a 1 to 10 scale, with 10 being perfect; they give their direct reports a 7.55 rating, and their co-workers a 7.39 rating.

Respondents view corporate leaders as the least productive workers (average rating of 6.72).
