Now, I don't want this ladder to slide, so now I have a requirement that the frictional force must be less or equal to the maximum frictional force possible.

我不希望梯子滑下来，所以我要求，摩擦力必须小于，或者等于，摩擦力的可能最大值。

That means low-level work experience at whatever price which is often the critical first rung up the work-force ladder.
