I said in a comment about a week or so ago on another similar story, that the main reason for the vax mandates is to increase union membership. All the large exemptions such as USPS and now the UAW are for large, strong unions who are big Democrat voters and contributors. The smaller companies and organizations employees have been more resistant to joining unions, but when they see the only way to avoid mandates is to lose your livelihood or join a union, more will do so. Biden has been pro union his whole parasitic, political career and this is his strategy to pay them back. There is no medical or scientific or logical reson why everyone is suppose to be mandated to get vaxed or lose your job but millions of workers in many of the nations largest unions get exemptions. Total bullshit, like everything else about this administration.
