In class, we created a skill$-$based pay structure together for automotive manufacturing. Which of the following is true about that exercise?

the overall number of workers was reduced to save costs

workers could back each other up if one was absent from the team

only one worker "topped out" meaning had Skill Blocks A$-$E

the differences in pay towards the top$-$end of the pay structure reflect the increased value of additional$/$newer skills

all of the above
