I co-manage a group of about 20 people, most of whom I only see once a week. Recently my partner (the other leader) fell ill and has been hospitalized with a serious illness. She will be in the hospital for a long time. Not only is this difficult, but her medical bills will be very expensive.
I want to ask my group for donations to ease some of the stress caused by her situation. However, the only time I can see most of these people in person is for a weekly meeting. I want to maximize the amount donated, but of course I understand people have different financial situations, so I don't want group members to see how much others are donating.
I have already sent a group email to the members telling them that I will be asking for donations during the meeting. I think most people in the group are kind-hearted, but I really don't want to make people who can't give as much feel uncomfortable. I also want to make the donations truly anonymous; I myself also don't want to know how much people have donated, as I don't want this to affect my feelings toward them regarding something that's not work-related.
I could ask for people to just stop by after the meeting, but most people just want to get out of there as soon as possible, and often I have additional things to handle immediately based on what came up in the meeting.
What is the best way to get as much money donated as possible while not making anyone feel uncomfortable about it?
