Unions were created, rightfully so, to combat early American corporate owners, capitalists, shareholders etc. from abusing them with long hours, unsafe conditions, zero benefits etc. as a way to increase profit. How does that theory and purpose even apply to a public sector employee?
States, cities, school districts, counties, state hospitals, villages etc. are non or not-for-profit entities. There are no shares, commissions, distributions, profits or capital to be grown by the entity abusing workers. The only source of income for the public entity is taxes -- YOUR MONEY. And if the entity abused workers - they would find themselves without the ability to provide services to the tax payer because the worker would find government employment elsewhere.
So what is a public sector union needed for? The corporate greed, capitalistic nature, and motivation that private unions were formed to protect against does not exist when you work for a public entity. In fact, they simply place the entity (which has no money) at the mercy of the unions' demands, with the only remedy to increase taxes. In a school district, the very members of the "administration" or school board that the unions are bargaining against are MEMBERS OR FORMER MEMBERS OF THE UNION THEMSELVES, and beholden to the union for votes.
Issue 2 is not only fair and practical - it is sadly needed to combat a union force that has no place in the public sector.
