work experience vs work experiences

I often see these 2 terms are used interchangeably.

It's very clear to me that 'work experiences' refers to specific job positions as opposed to the more abstract term work experience, which can be related to skills and the ability. Just to confirm, is this correct?

Note that this question isn't about differentiating experience(s), but is 'work' oriented.

Solution 1:

No, it isn't correct. The specific job positions that a person has held would be that person's "work history" or "employment history".

"Work experiences" is not a common expression, but it would be understood as referring to things that you have experienced during work; these things could be specific incidents (such as "dealing with a dissatisfied customer" or "facilitating a coworker's project") or specific environments (e.g. "working in a startup" or "working at a family-owned business").

"Work experience" refers to how much and what kind of work someone has done. You are correct to say that it is related to skills and abilities. A person's employment history would give a detailed picture of that person's work experience.
