Hi...
When we lift an object, two forces act on it. Those forces are muscular force and gravitational force.
We lift the object up with the muscular force so it does the positive work
But the gravitational force stops us from lifting it up. Therefore it does negative work.
Hope it is clear enough to understand and helpful....^_^
