How can one collect evidence to prove ageism in the workplace?

You can record the conversation you’re participating in, which is called “single party consent.” Although you have the right to record the conversations you’re a part of, you’ll have to get the written permission of everyone participating in the exchanges to record them, defeating the whole purpose because everyone will talk carefully. Make sure to keep track of every negative and ageism-related behaviours you face in your workplace, preferably in a journal with details like date, person, the topic of conversation, and the actual negative or ageism-related comment. After collecting the needed evidence, you may proceed with the right actions (based on your area) to prove ageism in your working space. This task can take a lot of energy and time, but we encourage you to take the needed actions to stand up for yourself and prevent this type of discrimination in your workplace in the future.
