Several critics noted the song's style is comparable with the musical style of the hip hop producer DJ Mustard. In a review published by the staff of Idolator, Robbie Daw called the track worthy based on previous singles with the titular name a called it the group's "most solid single to date." In a mixed-positive review, Carl Williott initially called the track a "DJ Mustard ripoff" but complimented the group for managing to make the song "their own" with their "subtle harmonizations adding some texture", he adds. Mike Wass shared similar sentiments and called it a "sleek and sexy bop with on-trend production" and an "insidiously catchy chorus" while praising the group's musical evolution. Several publications thought it was a strong contender for song of the summer. However, other critics were not so positive. Christopher Bohlsen of Renowned for Sound gave a negative review, saying that while vocal melodies in the verses were "satisfying", the chorus just "doesn’t sound interesting enough", calling it an "utterly standard pop song". Bohlsen gave the song a two-and-a-half out of five rating.
Matt Collar from AllMusic described "Work from Home" as one of the "most playful tracks" from 7/27 writing that said song along with "Not That Kinda Girl" "build upon Fifth Harmony's knack for mixing juicy R&B hooks with just enough hip-hop muscle to keep things from getting too polite." Maeve McDemortt from USA Today agreed, citing it as a highlight and praising its production. The Boston Globe's writer Maura Johnston called it an "Afternoon Delight", similarly, Brittany Spanks from Rolling Stone described it as "an "Afternoon Delight" for the smartphone generation that fluttered by on minimalist synths." Carolyn Menyes of Music Times gave it a positive review, noting the "chilled out vibe" and the "chorus that cools down the song's momentum rather than pumping it up".
