Working hours changing constantly, disrupting life management outside working hours.
High pressure on results, leading to being very stressful, sometimes I couldn't sleep
Sometimes you receive downvote by customers by mistake, or because they don't like the company you work for, but manager and supervisors don't and won't care, they look at percentage of customer satisfaction, full stop.
Short contracts (3 months) leading to be constantly worried about the future
Contract was not renewed after 7 months, despite all the efforts to improve the idiotic percentage (ironically I was within their target in the last month).
I will not work again for this company. A place to avoid.
