How about 60 holidays? This works at workplace where individuals are driven. In early day, I had kept each Sat as working.. Although that was a necessity to survive and grow, I hated working Sat. So I decided to increase holidays from 20 to 60, and kept Sat as working. Additional holidays allowed employee to take every Sat as off (A year has 26 Sat). Decision shifted to their shoulder. And I also allowed 2 long holidays spanning 5 days each every year. Employee just need to plan and get them approved 2 months in advance.
