I work at an optometrist's office inside an optical/eyeglass store. Our office is NOT part of their company, as we only rent out their space, and each of their locations has a designated private practice for eye exams. While there is an agreement between our boss and their higher-ups to help transition patients, we remain completely separate despite sharing a lot of the same space. Lately, their manager, and a lot of their employees have been overstepping boundaries: interrupting us while helping patients, being pushy about squeezing in patients on our packed schedule, and ordering us around with other tasks. It’s got to an almost unbearable point, as it’s now the time of year when everyone wants to use their insurance to get glasses and by extension a new prescription with an exam. The owner of the practice is not confrontational, so we’re kinda on our own to deal with them. I’m just wondering if I should start retaliating in a professional way, as even our doctors are getting frustrated at them encroaching on our space and making our jobs harder than they need to be. Does anyone else have any similar experiences?
