Good luck with your proposal. I work at a non-profit as well. Our charity has a diversity policy that they are trying to institute province wide. It has helped open dialogue in some offices about culture and how it affects the work place. Luckily I work in a very small office and my co-workers are really nice people.

Oddly enough my boss poked her head in my office the other day and asked "when is kilt season it should be soon!" A co-worker and I last year wore our kilts to work on St. Andrews Day, the Friday before Burns night and Tartan Day. I think she is just looking for the home made Cock-a-Leekie soup I bring to celebrate Burns's Birthday.. but you never know.

Good luck again,
Sara
