I worked in retail for a number of years and the overwhelming majority of people I worked with were very hard workers who took their job very seriously. And the pay was sh1t!
That's always been my philosophy, your work ethic is your work ethic..........you don't adjust your work ethic to match the pay.........you quit and go find a job that pays fairly. (after a polite discussion with the employer) If a wise employer can see you making more money for you, he won't let you go.
