Pros
Excellent company. Owner is a Pharmacist who works in the field so he doesn't place unrealistic expectations on employees and he treats them with respect and understanding. All work assignments are optional, so you can choose your days off. No minimum hours required. Within a year, I had worked at countless retail locations as well as small community, hospital, LTC, and was even able to work in a vaccine research trials setting, which was unique and interesting! Everywhere I worked the clients had massive respect for the owner and his organization. Evidently, they have a history of rescuing pharmacies at a moment's notice with a very high success rate. Although the introductory pay rate was low, it was raised shortly thereafter, when I had proved my value. When I applied for my dream job, the owner wrote me a recommendation letter and made some phone calls, virtually ensuring that I got the position.
Cons
If you need to have your schedule laid out months in advance, relief work is not for you. There is plenty of work available, but the clients schedule 1-2 weeks in advance, on average.
