TFA didn't address the one thing that, in my experience, has been the raison d'être (at least in my city) for large employers to generate lots of emergency medical calls.

SICK LEAVE POLICY

We get a ton of calls to certain call centers in our area while other large centers generate very few. When management isn't hawking over the patient, I ask them what the sick leave policy looks like. Generally, they can only take a limited number of sick days without triggering some kind of adverse metric that will impact their employment. These metrics can be measured in points, stars or some other arbitrary method to keep track excused vs. unexcused absences.

If you call out sick, that would score the highest in terms of adverse action record keeping. If you "go down" at work, you have more options and the metrics do not generally apply. You can also file a workers compensation claim which you can not generally do from home with a cold. Whether or not the claim is accepted by the insurance agency is another matter entirely. However, it is not a stretch to see why a bad sick leave policy would lead to employees figuring out ways to circumvent the policy without damaging their employment status.

These types of abuses, again in the states, are so prevalent that we joke about it at the station. The EMS system is abused from top-to-bottom and there is nothing to hold anyone accountable. It is simply going to break someday and that will be that. I can say that it seems the day when there are no ambulances available is drawing closer and closer... It already happens a few times a day in my city.
