Sticky Floor Metaphor

I ve always liked the poetry of metaphor with its imagery revealing nuances hiding shyly in the background.
Sticky floor metaphor. Expression used as a metaphor to point to a discriminatory employment pattern that keeps workers mainly women in the lower ranks of the job scale with low mobility and invisible barriers to career advancement.

Whereas the glass ceiling evokes the idea of a barrier preventing access to management grades the sticky floor focuses attention on the first stage of progression where discrimination can be experienced. The sticky floor metaphor is one where women somehow hold themselves back either unwittingly or by design.
Whose undoing is not so much out there but in here. In the literature on gender discrimination the concept of sticky floors complements the concept of a glass ceiling. Is a metaphor sometimes used to convey the difficulties that disadvantaged groups experience in moving from the bottom of the organizational hierarchy. Trippingly on the tongue.
Words alone sometimes convey their meanings too narrowly whereas metaphors allow imagination to roam more freely only loosely tethered to definitions.
