Then recently, after 4 yrs of rendering a regular 9.5 hr shift, we are asked to sign another document, amending the 9.5hr back to 9 hour shift retaining the "rice allowance" and "laundry allowance". We suspect that somebody complained the 9.5 hour shift and won.. and because of the rule on diminution of benefits under the Labor law, the extra "allowances" were not allowed to be discontinued. Now my questions are:
1. Was the signing of the document even legal since our law says the normal hours of work under the Labor Code is 8 hours in one work day?
2. Can we demand our company to pay us the 30 mins OT that we've worked on for the past 4 years?
