I worked at Pizza Hut for a few years and to be quite honest I would not recommend it to anyone.
A typical day consisted of very busy/understaffed shifts where management would hardly do anything and staff members were working to their hardest and fullest in order to serve and help customers.
Staff morale was at massive low, management were incredibly patronizing, rude and insensitive to the needs of their staff members, it is not recommended to work for them part time, especially if you are a student, as they will put you on shifts even when you have informed them of your availability. Some even insulting staff members behind their back.
There was an extreme sense of favoritism in the workplace, many being praised and let off easily for small mistakes and slacking off when others were patronized and mate to feel inferior.
Tipping seemed to be a problem as well, many front of house members losing tips due to the server/server assistant protocol, along with the fact that some servers were not keeping a diligent eye on their sections.
All in all, I would recommend looking elsewhere for a front of house or back of house position, working in such a toxic environment will cause more harm than good.
poor management, low staff morale
