Timing the start of something is not a simple process. Punishing people for being late disproportionately impacts poor and disabled people. Not all of us can drive a car or even have a car to drive. We might have to wait on other people, or use public transportation, and the more steps we add to the process the more likely something is to go wrong. Punishing people for being late is systematic oppression towards these groups. This punishment can include starting without people, especially if that itself is framed as a punishment.
“Let the late ones be late and miss out (they can read the minutes), and reward the prompt ones by not wasting their time” From the rusty's rules of order, something the IWW uses to organize. They are ableist.
On the other hand, waiting too long to start can impact people with limited time or energy. Not everyone can stay awake an extra hour just to wait for something to start.
This means that there is not one singular solution for how to start things (although obviously don’t do punishment). In small groups the best solution is to talk things over with everyone and get an idea for what everyone wants to happen, what can go wrong, and plans to mitigate any potential issues. If public transportation is running late, maybe someone with a car can go pick you up.
For large groups, most things do not need a strict starting time. If it is a large group and it requires strict attendance then you brought hierarchy into it long ago and ableism and such was always the conclusion you were going to get anyways.
edit:
organizing in a way where disabled people are inherently accommodated instead of shoved into some “extra” system makes a big difference
to reply to those below, it is "entitled" to think that it isn’t ableist to force people into systems instead of building systems around the people there.
to put it simply, if a group is organized in a way where you must actively decide to favor one social group over another systematically and it is always the same group, you failed and are just doing hierarchy, in this case on the basis of ability. It doesn't matter if you can't imagine organizing without ableism, that is still ableism.
I got a discord linked in my bio for people who are a fan of that form of organizing, as you can see here it isn't common even in these spaces
That's just it. The sacrifices that a poor or disabled person has to make to be on time for their doctor's appointment are much greater than the ones their typical patient has to make. We all have to make sacrifices for punctuality, but we're not all asked to make the same degree of sacrifice.
It's just that the logical conclusion here is that everybody skips work/class/get-togethers/volunteering on days any individual is sick or has problems, and therefore effectively nobody can ever do any work or receive any benefits from any work or community activity of any kind. At some point some things have to start on time, right? From surgeons to airline pilots to garbage collectors to graduate classes to stamp collecting clubs to backyard BBQs, delaying everything until everyone can do everything at the same time just doesnt seem like it would work
The argument isn't that everyone should be allowed to come whenever they want, but rather we should assume good faith and not intentionally punish people for being late. The natural and social consequences are more than sufficient for whatever misguided purpose the punishment is meant to serve.
Ah I thought the argument was that there shouldn't be any natural or social consequences either per the assertion the IWW's language was ableist
