Hi Ed - No offense taken. You had no way of knowing this but my entire career has been in the nonprofit sector and I have volunteered pretty consistently for the last 20+ years (literacy tutor, youth services, homeless shelters) etc. or served on boards (which I am currently doing). And as I've worked in the sector, I know the value of cash contributions and regularly give to organizations and causes that are important to me as I know that volunteering does not help pay the rent or basic costs of nonprofits.
I have also managed volunteers throughout my work and appreciate that sometimes, you can have too many volunteers and there may not be any need for more on any given day or any given project, which I imagine may often be the case on Thanksgiving and Christmas at shelters or community organizations. It's just that this is my first year spending Thanksgiving in Chicago in a long time and I thought people here might know about some smaller, overlooked agencies that may not have the capacity and staff to recruit and manage volunteers that some of the larger agencies do. So if anyone does, please let me know.
