Gene Siskel of the "Chicago Tribune" gave the film 2.5 stars out of 4 and wrote, "The most pleasant surprise is the appearance of Dolly Parton, who with this one film establishes herself as a thoroughly engaging movie star. The biggest disappointment is that this Jane Fonda comedy about a trio of secretaries out to get their boss doesn't have more bite ... Instead of getting darker and darker, 'Nine to Five' gets lighter and lighter until it loses most of the energy it established so well early on." "Variety" stated, "Although it can probably be argued that Patricia Resnick and director Colin Higgins' script at times borders on the inane, the bottom line is that this picture is a lot of fun." Kevin Thomas of the "Los Angeles Times" wrote that the film "appears to be an audience pleaser that never misses an intended laugh. However, it strays so far from reality for so long that it threatens to become mired in overly complicated silliness and to lose sight of the serious satirical points it wants to make. Happily, it does pull together for a finish that's as strong as it is funny."
