Solidarity rounding is a practice of collectively rounding up or down a monetary amount to the nearest whole number, with the intention of donating the difference to a charitable cause or organization. This act of solidarity not only promotes a sense of unity and support within a community, but also allows individuals to make a positive impact through small, yet meaningful, contributions. Solidarity rounding is a powerful way to demonstrate compassion and generosity towards those in need, while also encouraging others to join in and make a difference together.
