How can I refer to a person who is working at a job for the longest period of time.
For example, imagine there are 10 people who work at the same office and one of them, let's say Amanda, has been working there for 10 years. The duration at which the other employers have worked at the office is less than 10 years.
What is the proper way to say that Amanda has been working more than the others at the office.
Is there any adjective I can use? For example can I use "oldest" in this sense? (However, this question is nothing to do with age for sure)
This example environment can be changed to a neigborhood,an apartment building, a society, an organization
