I am very glad for you that you see some positive things in these days. Wish everyone could be like that. Unfortunately, I do not and I will probably never be like someone who does. Call me a realist or whatever you want.
That being said, I remember with my previous employer, a minister one day had a meeting and informed the CEO that they need to embark on a mission to promote only 'good news' in the workplace. The minister gave a recommendation that employees who continue with negative speaking against the ANC should be fired. The employer would have full government backing if such employee ever decides to take legal actions. This seems to be widespread now and probably how many people are being influenced.
