I am sorry for these frustrations. In regard to sick pay, no law in Washington requires employers to offer sick pay of any kind and so employers are generally free to determine how and when such time is earned, used and accrued. This most likely means that employers may take earned time away in accordance with a change in job classification to part time if part time employees are not eligible for paid sick leave.
Regarding insurance, if you were no longer covered then your employer definitely should not have been taking money out of your check for premiums that were never paid. What you would want to do is call the health insurance company and as when the policy was cancelled. If the policy was indeed cancelled and you were not covered for any period of time for which premiums were deducted from your check, that would be improper and you would have the right to be reimbursed for that money. However, if you were covered during the period of time that money was deducted for premiums, that would be proper and there would be no claim. The first step is figuring out what your actual coverage period is.
