In Snow v. ALCOA, 15 Ark. App. 205, 208, 691 S.W.2d 194, 196 (1985), estoppel was invoked because the employer falsely informed the claimant that upon retirement he could draw no further compensation, and the claimant relied on the representation to his detriment because by the time he found out that he could file for additional benefits the statute of limitations had expired.
