This is one of those movies that - while it's so dated, the outfits are hideously scary, and the hair is somewhat questionable - has still managed to remain hugely popular due to it's great storyline, and comedic genius.
Three women - Judy, a somewhat shy recently divorced Housewife, Violet, a widow striving for promotion in a man's world, and Dora Lee, a sweet but ballsy country girl who's misunderstood as the office fluesy - forge a bond after their chauvanistic boss, Franklin Hart gets on their bad side.
Hart keeps Violet under his thumb while still having the nerve to steal her ideas and undermine her; Violet is over-qualified, and elligible for promotion, yet overlooked by Hart because she's a woman. Hart spreads lies to colleagues that he's sleeping with Dora Lee, which causes her to be an outcast in the workplace. He manages to reduce Judy to tears and threatens to fire her on her first day, after a mishap with a malfunctioning photocopier occurs.
The three women gather together and forge a bond over their troubles with Hart, but things start to go horribly awry when an accident involving Hart takes place, then turns into attempted blackmail.
An opportunity arises, and the women decide to take control, make Hart suffer, and at the same time, make changes at work and show at the end of the day women are just as capable of succeeding.
This movie is full of some great comedic moments, some hilarious fantasy sequences, and that general "feel good" vibe that makes the whole thing worth while watching.
