Fear of huge student debts and energy drinks are what keep call centres going until midnight.
Work almost any shift in a call centre and you will see energy drinks scattered around the place. On Sunday the office is full of aching heads from a drunken night forgetting they work in a call centre, on a Monday night it's students covering up the bags under their eyes because they have to work from nine am until midnight.
Working late in a call centre is not conducive to sleep, after tea and pushing my kids to bed stress and caffeine would keep me awake, the problem was without the Pepsi Max my perky personality would drop late, and being perky, happy and alert is what kept my job. Caffeine gave me incredibly trippy dreams making me feel like I never really slept.
Call centre work is very hard on your voice, talking for hours is my specialist skill but call centre and have to speak more clearly than talking between mates, caffeine dries up your throat so you can find yourself croaking your way through shifts for months.
Caffeine is a drug that keeps people chatting and working through some incredibly difficult and busy lives and pressure and demand keeps people working through busy lives, so the next time you ring or email a cal centre late there may well be an exhausted student answering your all, be gentle.
