I have four styles - down (straightened if I have enough time), pony tail, bun or side plait. I have done two plaits when I've been on holiday but never for work.

Whether it's up or down depends on whether it was a 'wash' day or not. I wear my hair down on wash days and up on non-wash days.

All the above work for me and I can do them in my sleep so I don't strive to learn anything knew. Lazy and a bit sad, but true.
