Wednesday March 8 marks International Women's Day, with festivals, concerts and exhibitions among the numerous events planned around the world to celebrate the achievements of women in society. The annual event has been held since the early 1900s and traditionally promotes a different theme each year, with this year's edition calling on people to #BeBoldForChange and push for a more gender-inclusive working world. Reuters photographers have been speaking with women in a range of professions around the world about their experiences of gender inequality.

Two women wearing nun outfits drink beer while watching the 2014 Tim Hortons Brier curling championships in Kamloops, British Columbia in this March 8, 2014 file photo. Although some people might conclude that a curling event could produce a dull atmosphere, it is actually far from it. Some of the most energetic and loyal fans are committed to showing their colours at tournaments around the world. There was a lull in the games that were being held on this day and I remember spotting these nuns sitting in their seats earlier. Although them just sitting there didn't produce a picture, I kept my eye on them for the entire match. As soon as I spotted them with beer in their hands, I slowly turned my camera towards them and waited for them to take a drink. One of the challenges of shooting this image was to not have everyone notice me taking the photo. I had a longer lens on and was right in the middle of the rink. I slowly turned my lens, not to make my intentions too obvious, and waited until they drank from their beers together. (Photo and caption by Ben Nelms/Reuters)
