Her experience about working in a company can be said to be very little. Due to the limitations of working hours that were too long and the income was less than the working hours that were too scheduled.
Cleo preferred to do part-time jobs that can make more money. Instead of having to wrestle too long with a job that could took up most of her time but couldn't produce anything that would be more profitable for her.
