Everyone is disinclined to work. That's what makes it work, and why you have to pay people to do it. The definition is a tautology.
I mean, if taking a pill can make someone less lazy then laziness must be a thing, right?
If you want to avoid lazy employees, and hire motivated self-starters, then "lazy" might work as a description. If a good employee is suddenly having problems and you would prefer to keep them, all "lazy" does is put a non-explanation insult on them, it doesn't tell you anything. "They lost a family member and haven't been sleeping properly and are exhausted" tells you something. "They just saw another team's project get cancelled on a whim" tells you something else. "They feel micromanaged and are frustrated" tells you something else.
