Can a Pharmacy Tech. work on the weekends?

The answer to that question is that it is really up to the employer. Just like in any position, so long as the information is given up front and there are no bombs dropped, then anything is possible. The weekends tend to be the busiest days in most pharmacies. Most pharmacies work around the clock and the chances of working something out are in your favor, so long as there is communication with the employer.
