Hey you--you with the increasingly rare opportunity to hire someone to work for you. These are tough economic times. Lots of people are looking for work, and you hold all the cards. That may feel good, but the people who are applying for those jobs do not feel so good, so this is an invitation to avoid the opportunity to exploit your hiring situation and, instead, treat applicants with compassion and dignity. You stand to gain from that, too.
Here are some tips:
First, understand that $10/hour is not a living wage for full-time work, much less for the part-time hours so many workers are offered. If you must offer a worker that kind of wage and limited hours, at least offer a predictable schedule so that she can find another part-time job. If you don't, you will likely find that no sooner have you invested in her training, she will leave, either for a full-time job or to move back in with her parents who live in another city.
