At my work we use an app for calculating hours/pay and there are request off options that the GM has notifcations turned on for. Other than that he would not know if I told him anything else through that app, and I wouldnt figure that he would. Without talking to someone I would figure it's on me to make sure someone actually recieves notice. A voicemail/text in the least if they don't answer a second time.. does this business not have a phone number to contact the building itself to just ask for a manager? (Legit question)
