There have been a myriad of versions since last year.
There's the Executive Yuan's 多元放假 draft, slashing 7 public holidays, but gives flex holiday so that people choose when to take time off, and adding Aboriginal holidays into law so that they won't be penalized for attending traditional holidays.
KMT has their own version of 多元放假 draft.
Executive Yuan has its own 一例一休 draft, and many DPP legislators have a small alteration to the Executive Yuan version.
Another DPP legislator 鍾孔炤 had his own 一例一休 draft, which he later withdrew and made his own alterations to the Executive Yuan version, including a whistle blower protection clause.
Another DPP legislator 蔡培慧 has her own 一例一休 draft, which will demand employer to make up an off day if they asked the employee to work on a rest day. This version would be much better than the 2 off day version.
KMT currently has their own 2 off day draft, and NPP also has their own 2 off day draft, and they borrowed 鍾孔炤's whistle blower protection clause.
That is just what's happening this year. This is my recap for what happened before:
Ma's administration officially slashed the 7 public holidays in December of 2014. As previously mentioned, the 7 public holidays weren't celebrated for 15 years, but Ma cut them officially so adjust for his 80 work-hours every 2 weeks policy. It was in effect on January 1st of 2015.
So when he slashed it, most high-tech businesses that were giving their employees 7 flex off days to offset the not practiced 7 national holidays decided to cancel those 7 flex days as well. At the same time, they adjusted daily work-hour from 8.33 hours to 8 hours.
For these high-tech employees, since they were operating under the system of job responsibility, they were already working over 8.33 hours anyway. So it's like giving them nothing and taking away that 7 flex days. So understandably, these employees complained, and TSMC was the first to decide to return the 7 flex vacation days. That was immediately followed by almost every single high-tech companies.
Like previously mentioned, those with specialized skills and more bargaining power don't really need the law's protection.
So that was KMT's original version. Since 2014, the KMT then had multiple 1 off day 1 rest day versions that got returned by the DPP for a very specific reason.
If you are interested, read this article to see why the DPP rejected the KMT's original 1 off day 1 rest day plans, but came up with their own version instead.
Back when CSB pushed for 2 day weekend failed, the KMT and the DPP compromised to push the 84 work-hours per every 2 weeks revision. However, KMT led legislature deliberately left out forbidding employers to change daily work hours. So what the employers did was changing daily work-hours from 8 to 7. That way they can make employees work for 6 days but still fulfill the 84 work-hours every 2 weeks requirement. What happened was laborers had to work for over 8 hours anyway, and they didn't get the 2nd day off.
When Ma pushed for the 80 work-hours every 2 week revision, their 1 off day 1 rest day plan deliberately left that loop hole open again. That was why the DPP blocked it so that it can be decided in the current session.
