You know what is an important workplace skill (tech or not)? Speaking intelligibly.
Some people seem to think that all criticism of accents is bad, because racism. This is actually backwards. I myself am an ESL speaker, and therefore have some trouble understanding heavy accents. Using people with heavy accents in a video instead excludes people who speak English as a second language, since we, as a group, are not trained in it. Our experience of spoken English have mainly come from TV and movies, where people speak clearly. So when we see something like this video, we are effectively excluded from understanding it.
Saying things like “was it really that hard” is condescending. Yes, it’s hard if you don’t have a lifetime of training, which people in English-speaking countries do. We ESL speakers don’t. Producers of videos should be more considerate.
I'm the only native English speaker at my company. Some folks speak perfectly, others don't.
The people in this video spoke though, even if they did have a fairly heavy accent.
Being able to understand ESL speakers seems like an increasingly important skill if you work in tech, was it really that hard for you?
