I work in a busy hotel and wages cheques keep bouncing every week until eventually after several visits to their bank branch they can be changed---very difficult for all concerned trying to pay rent and just live on poor enough wages as they are---anything we can do without going to mgmt an we have no union.
If the Hotel is as busy as you state, there is obviously another issue with the cheques as they are bouncing. The hotel is probably / possibly owned by one of the Galway property developers. If the cheques are bouncing as often as you make out, Failte Ireland should be advised of this and the Hotel should be declassified of its rating.
If you can’t be paid in cash you should ask that your cheque be cashed on the hotel premises – either out of petty cash, reception till, bar till, restaurant till etc.
