Trust & Safety Coffee Hours are one-on-one conversations designed to provide mentorship to current and aspiring trust and safety professionals. Hosts are volunteering their time and expertise to offer advice to job seekers and T&S professionals. Hosts are not conducting formal interviews, offering referrals, providing product feedback, participating in interviews and/or user research, and/or acting on behalf of their employers or TSPA. If you schedule time and you’re not a current or aspiring T&S professional, a host reserves the right to cancel the appointment without notice.
Here’s how it works:
- Search for a host based on what you want to talk about. Sign-up using the host’s “Schedule a chat” link.
- Be respectful of our hosts and their time. Remember the TSPA Code of Conduct applies to all resources, spaces, and programming–even if you’re not a TSPA member.
- Because these one-on-one conversations are brief, come prepared with questions and have a specific goal in mind. If you’re just getting started in T&S and want to learn more, we recommend reviewing Careers in T&S and the T&S Curriculum before scheduling.
If you’re a TSPA member looking for a way to help other folks on their journey in T&S, sign up to be a T&S Coffee Hours host!
