Scientific Symposium: Blindspots in Diversity Management

On January 17th 2019, I organize a scientific symposium on Blindspots in Diversity Management at Leiden University.

The aim of this symposium is to showcase the state-of-the-art social psychological research elucidating important issues for organizations to address in their efforts to successfully manage diversity at work. Topics covered include the ironic and unintended effects of diversity structures and interventions, the importance of inclusion, invisible forms of diversity, shared impact, the subtle psychological mechanisms by which workplace inequality is maintained, and how scientists can contribute to improving organizational practice. 

The program features a keynote by Cheryl Kaiser (University of Washington), research talks by Seval Gündemir (University of Amsterdam), Colette van Laar (KU Leuven), Thekla Morgenroth (University of Exeter) and Jojanneke van der Toorn (Leiden University), and an interactive session on improving organizational practice (with Naomi Ellemers and Wiebren Jansen; Utrecht University).

This symposium has a scholarly focus but may also be of interest to practitioners. Admission is free.

Registration is closed

LUMC Pride Seminar

Today, I will be giving a keynote lecture at the Leiden University Medical Center. Join us!

“We are proud to present Professor dr. Jojanneke van der Toorn from Leiden University who will give a lecture regarding LGBT Workplace Inclusion.

More and more organisations acknowledge the importance of an inclusive workspace that accommodates sexual orientation and gender identity. This workspace is hard to realize since an apparently tolerant space is often in fact not so tolerant at all. Persons who support equal rights, can disapprove of a transgender colleague or make remarks that are (unintentionally) hurtful about homosexuality. To promote inclusion of lesbian, homosexual, bisexual and transgender employees (LGBTs) at work, knowledge of the social psychological mechanisms that are the foundation to their stigmatisation is needed. To determine what works, we need to know why something else does not work. This is the added value of a scientific approach. Jojanneke van der Toorn discusses the psychological processes that stand in the way of a truly inclusive workspace for LGBTs and what we can learn from them to find practical solutions. Because inclusivity offers opportunities for both employees and organisations.”

Pride Amsterdam 2018

This week I had the pleasure of attending a conference and of partying on a boat in the Amsterdam Pride Canal Parade, both organized by the Netherlands Institute for Human Rights.

To be LGBTI is a human right
Alderman Marieke van Doorninck opened the conference by stressing the importance of diversity for the city of Amsterdam. Then sociologist Jan Willem Duyvendak explained the term homonationalism, and argued that viewing LGBTI acceptance as typically Dutch polarizes the debate. Boris Dittrich moderated the afternoon which also included contributions by Marja Lust (Police), Annelies Tukker (Nederlandse organisatie voor seksediversiteit), Isjed Ijaz Hussain (Stichting Prisma Groep & Veilige Haven) en Milan Hendriks (transgender). I gave a flash lecture on LGBT workplace inclusion.
