FT Executive Appointments launched its weekly haiku/senryu contest in 2014. Winning poems covering specific workplace-related topics are published in the section on Thursdays.
To enter, find the current topic in each week’s Executive Appointments and send your poems on that topic to firstname.lastname@example.org.
This week's theme is First Day at Work
Entries must be previously unpublished and the writer’s own work.
