hardest working
Least likely slacking
Hardest working is the superlative form of hard-working, describing someone who exerts more effort or dedication than others in a group: She's the hardest working person on the team.
The phrase often carries admiration, though it can also imply overwork or exploitation: The hardest working employees don't always get promoted.
