Yes, nursing is important.
But your employer makes the most money on Thansgiving, more than anytime of the year.
Your employer, if closed over the holidays, would have to layoff employees.Your employer may go out business. That is the fact.
If you feel that your employer needs to make less profit- then find another job.
You are not doing your employer any favor by continuing your employment with them.
Maybe if business cut their prices throughout the year instead of on just one day, it wouldn’t come to this.
