The U.S. Chamber of Commerce, while not addressing the regulations themselves, did express that went into them. "The ADA amendments reflect a carefully crafted compromise between the business community and the disability community that was passed by the House and Senate without dissent," the Chamber statement said.

CFOs and other executives will want to be aware of several implications of the new regulations, Creighton says. For starters, while the concept of reasonable accommodations doesn't change with the new law, the pool of employees who can expect accommodations just got bigger. In addition, they shouldn't assume that a particular condition, such as social anxiety disorder, is minor and thus doesn't warrant some sort of accommodation. "Don't make those assumptions," she says. And, CFOs who work with larger companies won't want to argue that an accommodation poses an undue financial hardship, Creighton says. "That's rarely going to be a winner. For a mom-and-pop company, maybe. But, if you're a large company, that analysis is generally not in going to be in your favor."
