在一个职位的薪水说明中看到这样几行内容: " L( y' N8 E6 [, R; K0 O+ O0 G; j& Ssalary range: i- a6 B* @' S/ a* Z* d
the rates quoted are in accordance with a collective agreement between the union and the city of edmonton! n, L8 r+ p+ ~. I" y

opportunity concept level 2: ............+ {+ T, E% U# U; l

3 个各标了3种不同的薪水标准, 想知道的是:到底哪个才是这个职位的薪水呢?还是说根据什么不同而不同呢?
