When potential employees interview for a spot at the company, they're often asked what role they would eventually like to take on at Pool Covers in the future. After they're hired, staffers are 'cross-trained' in duties of other jobs (in addition to their own), so that they can be easily promoted if a position becomes available. It's not uncommon for someone to start as a file clerk, and within a few years transition to a managerial position. CEO Claire King began her career as an office assistant.
