Legal Question in Business Law in California

Re: Employment termination

California is an at-will state.

This means that an employer may fire any employee at any time, for any reason or for no reason at all.

There are a few exceptions:

1) If there is a contract between the employer and the employee for a set term;

2) If the termination is the result of employee's membership in a protected class (age, sex, race, religion, national origin, etc.)

So unless the sick day was protected (such as for pregnancy or due to a disability) the employer can terminate.
