This is happening right now at the grocer I work for. People have been getting their hours cut for months. One full time employee got 12 hours last week.
Then people earning higher wages began getting fired for nonsense reasons, like not having a paid sticker on things like coffees and such, which they had reciepts for.
Last night management drastically cut hours and didn't inform anyone. Multiple people came in at their scheduled times only to find they were now scheduled for 4 or 5 hours later.
I talked to multiple people and eventually found out that this company is in the midst of a buy out and they using atomic measures to fluff profits.
Areas meant to be staffed by 10 people are staffed by 2. There are lines stretching from the registers to the back of the store. The store managers are trying to fill multiple positions at once and simply can't, while dealing with the ire of every employee present.
This is why we need unions for EVERYONE. This is why we need legislative controls on predatory business practices. These people can't function without our labor and consent. We need to flex that muscle. We need nationwide labor walk outs and unionizing.
