only the first days at any...

[color=red]1-Only the first days at any job in our office are difficult.

Doesn’t this imply that tehe first days at every job in our office are difficult? There is no job in our office that is not difficult during the first days.

Obviously, in all cases, the job becomes easy after the first days. But the first days are hard, no matter what the job is.

Am I correct?

Gratefully,

I would understand it to mean what you say, but it’s a pretty awkward sentence. Best to say it another way, such as “The first days at any job in our office are difficult, but then it gets easier.”
