First time posting here, not sure if I am being unreasonable but I work as a pharmacy technician for a uk pharmacy chain which has a few branches spread out in the area where I live. I am contracted to work 30 hours per week in a store about a 10 minute drive from where I live and as dh and I share a car he leaves me to and from work each day before leaving for work himself. Recently there has been a shortage of those who can perform my role in my area and my manager has given my mobile number to various other stores without my permission and now I am inundated with calls on my day off from other stores looking for me to work for them which I cannot do as I have no means of making a 30 mile round trip to the various other stores. This is becoming very annoying as it has been happening every week and I have explained the situation multiple times to my manager who seems to think I should be making an effort to be available to work in other stores. This is not in my contract. AIBU in refusing to work in the other stores?
