There are all sorts of arbitrary requirements to behave in certain way as a proxy of achieving results. Unfortunately this is quite common as it makes the manager feel safe and in control if his subordinates achieve the results in the way she expects them to, but it raises the bar high for no benefit to the bottom line.

> submitting sick days without notice

Who the hell knows when they're going to be sick? I've never heard of such a thing.

Well, if you get a common cold, then sometimes you can feel whether it is manageable, or starts getting worse.

Then you'll have a whole working day, where you are functioning at like 50% capacity, and at least you can pass on your work which might block others to a colleague.

In my experience most of the time this is the case.

Reporting in sick in the morning all the time can be quite distruptive in some jobs.

If I were in this situation I would look for a job where there is more flexibility in this regard. Or keep an up-to-date document where I list all the ongoing tasks and their statuses and next steps (this would probably add a lot of overhead though)

Or, you know, it can be much more disruptive to coworkers that may not handle illness as well, or have vulnerable family members or housemates. It's selfish to the extreme to expect others to expose others to disease because of a mild inconvenience. Saying that as someone with multiple disabilities and who gets severely ill from cold or flu, is grateful when people don't deliberately act as a totally irresponsible adult and expose me unnecessarily. I can be be nearly bed ridden for multiple weeks but almost never get sick with people being courteous and doing everything possible to limit exposures to others.

The only thing I've pointed out is that repeatedly missing workdays (it doesn't matter whether you work on-site, or remote) without others knowing it in advance can be disruptive in some situations.

This is similar to planning an activity with a friend, and them not showing up. If they do this to you multiple times; you waiting for them and they do not even answering their phones, will you plan your next thing with the original enthusiasm? Or will you think "oh god they wont even show up, whats the point of planning anything".

This has nothing to do with disease or disability, this is just a simple break of promises multiple times in a row.

This can be avoided though, simply make promises which can be kept; do work, which can tolerate unforeseen absences, or work in a different way than others which compensate the issue in some way that is fair for and agreed upon by the other teammates.

I have my own fair share of health issues, and managed to choose a workplace which accomodates my needs.

Some people are not that lucky to have the opportunity or even ability to do that, but this is not in the scope of responsibility of an average citizen to solve.

I had a colleague once who has IBS, but also he absolutely loved pizza. So, while he never gave notice, everyone knew he would not be in on Mondays because he ate an entire Domino's XL pizza the evening before.

There is that story with the monkeys trying to reach a banana, and sprinkled with water, then eventually all of the monkeys replaced, and they prevent eachother from reaching for the banana, but they no longer know why.

Lots of stuff work that way, and we have a limited capacity, and tolerance to try which is useful, and which is just an "everybody does it like that" fad.
