that's not a political stance - that's negotiating your working conditions. It's private and individual, and only affect you (and your colleagues). It doesn't affect society at large whether you have on-call or how sick days are counted _at_ your place of employement.
But to use your position as an employee to push for universal sick leave, or for BLM, which affects society at large, not just yourself, is a political stance.
Also what about Maternity leave? Paternity leave? Are those not political?
How is negotiating working conditions not related to "how we engage and collaborate with each other as a society"? It's inherently (little p) political even if the engagement is at a company similar to how politics on your local HOA is still politics.
edit: typo
No. That's an "it depends" thing. If the "political issue" in question is something team or working condition related then it's not necessarily private and individual affecting only you.
Some people will care about that and want to potentially co-ordinate. Other people won't consider it important, and/or have other priorities.
You must be aware of the existence of unions. You're mentioning US-political concerns, so you're almost certainly familiar with the notion that the mere existence of unions is highly political. Whether or not you are a union member, union activities effect US workplaces.
Ignoring their existence in this discussion is itself a political position.
You must have missed March and April when sick days at “essential work” (such as grocery stores, restaurants, coffee shops, and more) was in fact a matter of national conversation: sick people going to work spread disease. The number of sick days was also of debate: most low wage jobs don’t offer more than 1 sick day a month or two. Not so good when someone needs two weeks off.
This kind of short sightedness and inherent support of the status quo as “it’s fine, I see no problem here” is exactly what the other commenter(s) are talking about.
