The idea of anti-boycott is to award and support companies which treat well their employees – to make a list of companies who reply to a list of clear criteria, for exemple highest paid employee earns not more than 20 times what the lowest paid employee does; wages periodically updated according to inflation; a percent of the profits is shared with employees etc.
The companies on our list will get a label which they can use in their publicity and everyone willing to support them with their money will be able to check the list and buy from them. This will be a form of solidarity among workers of all different spheres, and also will motivate business owners to improve their employees' conditions while also being benefitial for their business and image.
