I have searched in Reverso Context to find out how to say in English that I want to work in a different field (one, not several). The expression I have found is change jobs.
But if I had literally translated from the French expression, I would have written change job without an "s".
I would like to know which translation I should use. If it's the translation with "s", why is there an "s"? Normally I quit a job to take one other job, not several jobs. Therefore I don't understand why jobs should be plural.
