What is this Japanese television series about secretaries... or maybe they're nurses?

I was in Tokyo in 1999 and watched a Japanese television show every afternoon when I came back from my wanderings around town. (Best things: soaking in the big mineral tub at the bathing house, the udon, the parks and temples, amazing skyscrapers, friendly people.) I don't speak a word of Japanese and the show was not subtitled.

The show seemed to revolve around a company, with bosses and seretaries. All the secretaries wore identical light blue uniforms, which made me think at first they were nurses. The plot seemed to be that the bosses would get into all kinds of situations and the secretaries would get them out. There was one tall, very beautiful secretary who was very memorable.

My questions:

What is this show?

What is it about?

Was it popular?

Is it available in English or in any other form?
