I worked at telemarketers as one their sales team member from 2013 to 2018 when my manager left us without any notice or explanation given we were doing good work but no pay raise was offered nor bonus paid out after years working hard! When you apply do your research first because there may be many other companies who say what looks like great things about them which could turn into lies once hired due care must always been exercised especially if it's money being made!! Do not trust this employer until proven otherwise.
