Just start asking your friends at other jobs how their benefits, medical, vision, dental, vacation, pension, sick days, holidays, personal days, guaranteed raises, cost of living raises, funeral leave/pay, jury duty pay, holiday work pay, disability pay, guaranteed overtime pay, 401K, Direct Deposit, voice in the workplace/negotiations, if they even have any of these at all. Seniority is the biggest one I like so the managers cant get away with only working, promoting, assigning extra work/overtime, filling easier routes/jobs/work areas to their buddies/good ole boys/babes/rookies/whitesonly/etc etc THE UNION PROVIDES A SENIORITY SYSTEM THAT PREVENTS DISCRIMINATION BE IT RACIAL/GENDER/AGE/OR OTHERWISE. It blocks the teachers pets and brown nosers from stealing what is rightfully yours. Join the union and fight for what is yours and your familes. There is strength in numbers. Make the union work for you.
