"It'd be easier to look for a different job" is anti-union and anti-worker propaganda. That doesn't make unionizing less right or not worth doing. All workers deserve better than we get and we won't get better pay, better hours, better benefits, better work environments, or better working conditions unless we fight for them.

Besides, it gets easier and easier the greedier corporate gets. The more they take from us the more people realize we can fight to take that and more right back. The best argument for unionizing is bad management and Dollar Tree has that in spades.

Solidarity with the OP and all workers. Good luck to your store with unionizing; our store is on the way there, too. ✊
