If we can make provisions for permanently disabled people to have jobs, then we can make provisions for
temporarily disabled people to also have jobs.
The article you are commenting on largely deals with large employers (Merck, Walmart), so your complaint about small companies is best directed elsewhere. Exceptions for small companies can be codified into law - GDPR does this, for instance, by letting small companies simply update their terms of service and avoid having to do some of the more onerous revisions to data collection.
And there is a simple formula to leveling the playing field for those people who do want to work, regardless of their bodies (if you are female and would like to have children naturally, you have no choice in the matter - your body will need some accommodations).
1. Increased parental leave (not just maternity), which enables gay parents to have equal rights, and which allows working moms and working dads to work out between themselves how they'll adjust to the baby, according to each of their preferences. It also accommodates the cases of single dads, single moms, etc.
2. Federally funded and regulated daycare. We can look to countries that largely required female manpower to get back to speed after WWII (specifically, Germany and Eastern block countries with high male casualty rates). They had no choice but to figure out how to get the highest percentage of women back to work AND producing children or risk economy collapse and a drastic decline in their population further than already suffered. The solution was efficient, state-wide, state-regulated daycare.
Actually, as an aside - such a daycare system used to exist in the United States, as well, but was revoked. Some speculate an aversion to anything vaguely resembling what the "communists" were doing as why.
