A study found that coworkers negatively impact productivity in three key ways: 1) 50% of respondents said coworkers' performance directly affected their own performance, 2) 48% were frustrated by coworkers missing deadlines, and 3) 75% had to wait on coworkers to complete tasks. When coworkers are unproductive and miss deadlines, it decreases individual motivation and productivity. The study suggests using project management software to improve communication, collaboration, and hold coworkers accountable to increase productivity.
