Worse, they are pro Union. Even when the company is willing to make an accommodation, if the union gets in the way, the Union gets first dibs on not allowing the accommodation to go through.
In all fairness to the court though, making exceptions to the union contract, even where there may be reason due to discrimination, would be more than a “de minimis” cost, as forced exceptions to seniority would cause discontent within the ranks and possible reopening of the negotiated contract (i.e. “burden on business operations”). So either way (whether you call it “de minimis” or “burden on business operations”) I believe TWA v Hardison was decided appropriately.
As we don’t know what your case was, I can’t speak to your specific scenario, but have to assume that the courts were correct in their decision there as well.
