My question involves labor and employment law for the state of: california
Before the new SICK LEAVE LAW took place on July 2015, our employer was providing us vacation benefits where an employee gets 40 hours vacation on his first year, then 80 hours for those who have been working with the company for 3 years and above. This vacation policy was changed by employer on July 2015 where employer eliminated vacation and changed it to PTO, in addition to the SICK LEAVE LAW where employees working with company 1-3 years may accrue 48 hours sick leave, but no PTO, and this who worked more than 3 years have 40 hours PTO plus the California prescribed sick leave law, 48 hours value. Is this legal? We believed it's not fair, because we were already making 80 hours (3+ years working) and the sick leave shouldn't be taken out from that 80 hours... and also, when employer changed vacation plan to PTO on July 2015, accrued hours were set back to zero, to start the new accrual, is this also legal?
