First phrase in the article: "Shortly before the German parliament's summer recess, lawmakers approved a whole series of reforms." Sounds like "done and dusted" to me. The Bundesrat (the second chamber of the parliament) also approved, er... something, but it's not clear to me if it's just the health measures or also the rest. What's left is for the Bundespräsident to sign it, but that's a formality.
And yes, no idea why the SPD is so on board with this - some measures, like having to provide a medical certificate from the first day of an illness (which in practice means you have to go see a doctor personally on the first day of sickness), are definitely not going to increase the dismal approval ratings of this government. So, for example, if you're prone to migraines, until now you would have simply called in sick for a day, now you have to drag yourself to the doctor, only for them to tell you (after potentially hours of waiting) "oh, you do look very pale and sickly today, you probably do have a migraine, here's the certificate. I assume you already took one or several headache pills? Now please, go home and rest."?!
