You must be out of your tiny mind. Once you accept the position, you belong to Lidl. You will work any hour and day that your Store Manager sees fit, and you'll work four hours unpaid overtime on top of each shift. If your Store Manager calls you at 04:55 and demands you come in for 05:00, well, you'd better get your undercracks on and get sprinting out that door, or you'll face disciplinary!
College? Ha! You'd better knock that on the head if you want to join Lidl. There's no "College" in "Team"!
You can many different contracted hours.
30 hours ect ect
