I answered this question for you almost a year ago, Franz. The answer has not changed since then. However, I will answer it once more, very completely. It will be the last time I answer this question for you.
Your post last year says that your employer does not offer vacation or sick days. This is LEGAL. No Federal law and no law in any state says that an employer has to offer vacation days, sick days, personal days, paid holidays, or any other kind of paid leave. It is certainly not competitive, but your employer is not violating the law by failing to provide this kind of time.
The Fair Labor Standards Act, which is the primary Federal law which regulates the payment of employees, allows the employer to dock the pay of an exempt employee in the following circumstances:
1.) If it is the first, or last, week of employment and you do not work the entire week
2.) If you are on FMLA*
3.) If your company offers a bona fide sick time policy with a reasonable number of days (not defined in the statute but generally considered to be at least five and preferably ten)
4.) If you take the entire day off for personal reasons
5.) If you are suspended for a major safety violation
6.) If you are suspended for violation of a written company policy to which all employees are subject and which relates to conduct in the workplace (drugs/alcohol policy, violence in the workplace, sexual harassment etc.)
* In your state, and in your state ONLY, at least some FMLA is required by state law to be paid.
Since your company does not offer sick days at all, if you miss a day of work because you are sick, they have to pay you for it and cannot dock you. See #3.
However, if you miss a day of work because you took a day off as a vacation or personal day, they CAN dock your pay. They are not required to offer vacation days in the first place and #4 specifically gives them the right to dock you if YOU choose to take a day off work.
If they tell an exempt employee not to come in, that's a different story. But if YOU decide not to come in, it's legal to dock your pay.
