Does anyone know about workers comp?

The requirement to take vacation / accumulated sick days is common to FMLA. NOT to Workman's Comp. Your friend is being screwed with.

HOWEVER... Workman's Compensation pay is typically LESS than normal pay. If that was the issue, then the "suggestion" she received may be correctly helpful.

Sadly, in many cases a lawyer is necessary to even get what's due you.
