Will look for any reason to put you into disciplinary.
Poor bonus scheme, even if you do hit bonus its not worth it.
No sick pay, regardless of how long you have been there.
Awful shift rotations. You WILL work 5/7 days full time. You could do any shifts between 8AM-8PM spread across any of these days. It would make sense to start between 8/9am everyday to make rota's easier, not in this company. My second final week I worked there I started at 7.55am, 930am, off (Wednesday), 10.30am, off (Friday), 830am, 930am.
Holidays are almost impossible as they judge giving you days off dependent if the call center can hold the volume of calls for that day. Normally, this isn;t the case due to sickness and low headcount because of high staff turn over.
