Cost certainty
Working under a collective agreement provides contractors the terms and conditions which pertain to our construction sector.  Wage rates, benefits, hours of work including all the terms of employment are laid out, so there is no guesswork. You can bid future work with greater certainty around what core costs will be. UA Local 527 also handles all of the administration for health and welfare benefits, pension and other payments to keep it simple.

Union Thoughts

The labor movement was the principal force that transformed misery and despair into hope and progress. Out of its bold struggles, economic and social reform gave birth to unemployment insurance, old-age pensions, government relief for the destitute and, above all, new wage levels that meant not mere survival but a tolerable life. The captains of industry did not lead this transformation; they resisted it until they were overcome. When in the thirties the wave of union organization crested over the nation, it carried to secure shores not only itself but the whole society.
