Many people on twitter have in their bio some sort of a disclaimer such as “Tweets are my own and don’t represent my employer”. In my opinion this is totally useless.
If I say something stupid related to my employer, the audience following me won’t say oh, he doesn’t represent his employer, it is just him. People don’t care and won’t draw such a distinction.
And if it gets worse, you will be sacrificed by your employer. No hard feelings, it is the deal.
That’s why I wouldn’t waste part of my twitter bio on something that useless.
