A work environment can be identified as the place that one works.  i.e. -in an office building in a cube, at home at the kitchen  table, from a car or truck, at a constructiâ¦on site. All are work  environments. We tend, however, to hear about healthy work  environments.. This can point to other factors in the work  environment, such as co-workers, air quality, ergonomic seating,  management (the boss!), child care, parking, noise, and even the  size of one's cube. A work environment doesn't require a job. It  requires that work has to be done in some place.
