Diversity mission statement

Taitem Engineering is committed to maintaining and increasing diversity in its workforce. Taitem acknowledges that this requires ongoing active commitment and continued effort and therefore commits to:

  • examine how our current workplace culture and procedures may perpetuate society’s historic and institutional forces of exclusion;
  • engage in practices that provide opportunities to people who might otherwise be at a disadvantage because of these forces of exclusion;
  • promote and undertake practices that will increase the diversity of Taitem’s workforce; and
  • foster a workplace culture that encourages a sense of belonging for everyone who works at Taitem.

We believe that a diverse workforce brings a wider variety of perspectives.

We believe that committing to this diversity mission will help Taitem Engineering to be more adaptable and sustainable as a company.
