The Prince George’s County public schools will be closed for students on Wednesday after hundreds of teachers asked to be off to join a national day of protest in which women workers have been urged to stay home. The Alexandria schools have already announced that classes will be canceled Wednesday.

The protest is called “A Day Without a Woman” and was organized in conjunction with International Women’s Day, with the aim of showing the importance of women in the work force.

As of 5:30 p.m. Tuesday, the Prince George’s system said about 1,700 teachers and 30 percent of the transportation staff had asked for the day off.

With those numbers, the system said, it could not transport students and provide proper learning environments.

The county schools had about 9,000 teachers in 2013, according to a system web page. The number of teachers who have asked for the day off is a little less than 20 per cent of the total figure.
