I've spent a lot of time doing charity work. No place is perfect, but it's not your place to change it.

If it's triggering you, then I would suggest you find another place rather than trying to change the way things are done.

I've found that to be an uphill and useless battle.

The key to enjoying charity work is to buy into the mission. Stay focused on the mission and not the details. Remember why you joined it and stay close to that.

Odds are this charity is larger than you, been functioning longer than you've been there, and without your input. However, its mission may suit you well. Stay with the mission.

If it's just not working, then I really would find another.

Ideally charity work should give both ways - to you and to the charity.
