"Work" is human activity. For example, children's play is work. All living things desire to go about their lives. Well-adjusted humans desire to work. Note that this does not necessarily equate to jobs.
Of course it is. Play is a very basal behavior we see in a host of species among their young. Its biological role is to build up musculature and social bonding such that the individual will be strong enough and socialized enough to do what is required to survive among the colony/pack/tribe.
