They are not treating employees like replaceable 'trash'. They are treating employees like replaceable workers. And this relationship goes both ways. Employees can treat their employers as replaceable. Although I haven't seen an equivalent loaded word for 'trash' in this scenario. And there is no reason to believe that the only reason she was fired was because she wanted days off. Based on her own testimony, which is the best version of the events for her, she had many times used leaves to care for her children and put her manager in a 'difficult position'. So she would have been marked as a bad employee. As for the union. A union of sellers of anything is called a cartel and is illegal, but if it's a union of sellers of labour then it is suddenly the shining beacon of equality. The only real difference is that union of sellers have way more voting power.
