If not in the almost exclusively investor owned media then in the attendance-mandatory antiunion propaganda meetings you will be forced to attend if managment start to fret.
There's no danger of not hearing the cons.
We don't represent the public. Whether we're working on behalf of the public depends on whether you think the government's position represents 'the public', and which part of the public you're most interested in. (The interests of childless taxpayers who don't believe in the importance of university education are not well represented by lecturers and their unions, surprisingly enough...)
I think what I'm saying is that some of the conflicts between unions and management are zero-sum, but others are not. And while public sector unions can narrowly represent a producer interest, that certainly isn't true of all situations.
It would be wise to question why the military was brought in to get rid of them - both in the UK or the US.
What's to say that founders, managers and execs bleeding people dry isn't also something equally "tired" given that in today's labor market, any such leadership will bleed out talent that will vote with their feet for greener pastures?
As a sibling comment said, unions have their pros and cons.
So yes, pros and cons with unions, but let's not forget where the balance of power is right now.
