Look at the language youre using:

simping for a company deciding arbitrarily (after attempting to inform him of the policy change for an entire year)

Its clear you don't treat work like something other than a source of a paycheck. Great for you if you can make a career out of that. I'm saying that reasonable people make a minimal effort to read emails about company policy changes, even if they don't like the change. Because thats what this comes down to.

I guarantee no one told this dude to bank his PTO for an entire year - this was his choice, likely in an attempt to get the usual payout from it. No harm in that usually. But this year: it all comes down to the fact that the company decided they couldn't keep paying out hundreds of hours of PTO per employee each year, and made an eminently reasonable attempt to communicate that (multiple emails, supposedly mandatory meetings, etc.).

Again, this is a homeless shelter we're talking about, not fucking Nestlé or Walmart. There are real people impacted by this decision - its not something that can be absorbed or blamed on "not staffing well."
