Business prudent my ass. Cargill should hire them back at lower wage or tell them to find another job that accommodates them.
Ok...guess you never ran a large business with hundred of employees before...
Back when I did, recruiting, hiring, training, getting an employee productive cost somewhere between $5K to 8K because of having to comply with the burdensome laws, policies, legalese, etc...
So saving that cost is business prudent...
Offering a lower wage is probably not legal if you are doing the same job or position...
