Claimant was employed as a B&B Helper, and had approximately five years of service with the Carrier at the time of his discharge. Claimant was discharged for accumulating more than sixty demerits on his record under the Brown System of discipline in effect on this property. The instance which triggered the discharge is one in which the Claimant was charged with sleeping on duty, and he admitted at the investigation that he was guilty. He was assessed twenty demerits for the offense, and that assessment carried his balance to sixty.
The Organization raises two arguments in support of its claim: that the assessment of twnety demerits was excessive for the offense; and that Claimant's record should have stood at thirty, rather than forty demerits at the time of the offense, and that this latest assessment should only bring his balance to fifty - an amount not warranting discharge.
With regard to the question of the prior balance, the record indicates that Claimant did, in fact, have a period in excess of120 calendar days without discipline, between October 22, 1985, C~DZ/- -(o
and February 22, 1985, and that he was not credited with ten demerits for such time. However, the Organization's argument fails for two reasons. First, as the Carrier points out, Rule 31-G-(b) specifically excludes from the period, days off due to personal illness, and Claimant had seven such days during the period in question. Thus, he did not have the requisite time with a clear record to warrant a credit.
Moreover, even if the Claimant had been entitled to a credit, he waived his right to challenge the record when, on March 13, 1985, he acknowledged that his personal record stood at fifty demerits. That acknowledgement, which appears in his record, constitutes evidence of his knowledge of the balance, and thhe time limit for him to grieve the matter expired long before the discharge. Thus, the argument has no merit.
With regard to the organization's second argument - that twenty demerits was excessive - the Board finds that the discipline was appropriate. The Organization's contention is based upon the fact that none of Claimant's co-workers roused him at the end of his lunch period, and, therefore, they shared in his responsibil- qc)o (- q 0
