I have a theory. Companies are always looking for a competitive edge to make themselves stand out from identical services. Fast food vs fast food, hotel vs hotel.
Having employees walk out when conditions are shit inconveniences everyone in the chain, customers first and foremost. If this trend continues, companies will get a reputation of being unreliable.
Case in point, the most recent incident of a Hilton hotel walkout. While I don't know the details, I now know that there is a chance if I book a Hilton hotel, I'm gonna be fucked in the lobby for hours. So I'll book my hotel elsewhere.
If I was running a hotel, I would consider treating my employees better. Let's be honest; not because they're not humane and care about us, but because they can now gain the reputation of being a reliable, friendly business that you won't have to talk to a police officer to get a room key. Reputations are valuable (who still thinks Subway is healthy?)
The plan remains: if a company fucks you, act. Do something about that. Even if they don't change their ways, I posit that competitors will to take advantage. The ripples in the pond will stretch far and wide.
