There are potentially many reasonable things to negotiate for. So far, all the information I can find is "stalled contract negotiations". Working without a contract is a perfectly valid reason to strike.

Things like making sure that AI isn't used in certain capacities to reduce the staff size wouldn't be unreasonable.

As of yet, the contents of the negotiation aren't public - so we can only guess.

In the meantime, the idea that everyone should be able to make Big Tech wages ignores the reality that most companies aren't Big Tech and have a revenue per employee that is a small fraction of it... and are running on much slimmer profit margins.
