As a retired teacher, I remember the time before unions when each individual went before the Superintendant & lobbied for a pay raise. Men were higher paid than women, if you were disliked for any reason, you got little or no raise. If you got pregnant, a married teacher was fired or laid off,
If you needed an emergency day to go to court, see an MD, bring a wife home from hospital with a newborn,etc. you had to give 2 weeks notice to the Super. & be docked a day's pay IF it was OKed.
Unions in the public area have done much good. Public servants should not be less favored than non-public.
Also the raise anyone got bore little relationship to the cost of living, so most of us worked two jobs to support the family.
