I want to add two thoughts to the already good advice you have received. First, if you choose to tell her you aren't coming in, you have to MEAN it Kids are masters at recognizing when our body language doesn't match what we are saying in words! If we are at all uncertain or feeling even slightly guilty, they will go for the jugular. No malice intended--just basic kid survival skills. Second, when you set a specific boundary, STICK TO IT. If you give in after 15 minutes, next time she will rage for 20 or 30 minutes. It sounds like the "slot machine" principle has all ready set in--maybe the next pull of the arm (or scream) will be the pay-off! A wise teacher once taught me the Candy Machine method of behavioral change. When parents try to change the "rules", as the kiddo understands the rules of the game, the behavior usually gets worse, not better. Because the child is angry. "It always worked before. Mom and dad are CHEATING!" Imagine a candy machine outside your office & every day, you put a quarter in the machine, pull the knob, & out comes the candy. But one day, the price is changed to fifty cents--but no one tells you. The next day you put in your quarter, pull the handle, but no candy. Do you calmly say, "Oh dear, it doesn't work any more" and walk away? Or do you get mad cause the machine stole your money? Do you pull the handle repeatedly, with increasing force, bang the side of the machine, maybe say some rude words? What if you pull the handle 20 times, kick the machine, and swear at it, and then the candy bar comes out! You will soon be putting in your quarter, pulling the handle, kicking, & swearing whenever you want your candy. But, what if nothing you do produces the candy bar? You will eventually give up & walk away. The mistake parents often make is they "delilver the candy bar" before the child has realized that the machine doesn't work the old way any more! I don't know if you should increase the cuddle time, or hang tough. But whatever you decide, stick with the plan. And good luck. Sounds like you have a CEO in training on your hands.
