Friction will work against force
All bodies with mass are attracted to the Earth by gravity, so when a body is raised you must do work to raise it. This work is equal to force x height, if force is in Newtons and height in meters, the work is in units of Joules.
Friction.
The question is incomplete. If the bucket is taken in a horizontal plane then no work is done If the bucket is taken in an inclined plane then work has to be done against force of gravity
Spraying lava.
Negative work
Friction will work against force
When people say opressed they mean that they OR the person was held against there will to do the work of someone else. for example being a slave is a form of opression.

In this case, you are not doing work against the force of gravity, but against the force of friction.
It is the force (weight) against which the muscles work.

Action: Force from muscles used to push against the floor.Reaction: Floor pushes body up.
The equation for work is: work = force x displacement or W = Fd Since the car isn't moving, it has a displacement of zero. This therefore means that even though the force applied by the person on the car may be extremely large, the work done will be equal to zero. For example, if the person exerts a force of 15000 N, the equation will look like this: W = Fd W = (15000 N) x (0 m) W = 0 J
