How can we combat ageism at work?

There are all kinds of workplace stereotypes that should be considered ageism. People need to pay more attention to these random acts. A birthday card that is supposed to be funny, for example, or a stupid joke about someone’s age.
As harmless as it sounds, these are toxic to all ages. Age-related marks could cause older adults to feel depressed or anxious. And they could cause anxiety about ageing for younger people.
However, the most severe case of work-related ageism I’ve seen is assuming people can’t handle their job because they’re older. I remember years ago, I was grocery shopping with my grandkid. He’s the sweetest kid, but he said something that got me thinking that day.
There were three cashiers at that supermarket; one of them was 50 something; he looked at that man and said, “Grandpa, let’s get to the other line; this man would crawl all day.” That was hard for me to hear, as I faced some difficulties at work back then.
So to answer your question, I’d say we should be more careful with our language and attitude. Communication is a crucial factor; if possible, talk about age discrimination you or your coworkers face with other employees. If that doesn’t work, you can speak to your HR.
