It makes me upset that something basic like not wanting to drink lots of alcohol with your co-workers has to be justified with a legal framing of "freedom of expression". And Mr. T was fired in 2015, it took 7 years for this case to be concluded in the French court system. Not that French is an important qualifier, I fully expect the American legal system to take that long as well. It also makes me upset that the media's framing it as being not "fun".
In actuality, most people don't have the funds, the time, and the gumption to go through with a legal battle. You of course need to find a new job, but in the meantime you have financial obligations, and those don't wait 7 years to be satisfied.
