My boss has taken one days pay off me for eight weeks, is this legal, I am on a salary.

Why? What is the explanation?

You worked and were not paid for the day?

We need to know more. It is certainly possible for an employer to reduce your pay for a period.

If you mean he reduced your salary by 20% for 8 weeks then yes, he can do that unless you have a written contract stating salary for this time.

At least one state has a labor law statute requiring that the employer give the employee advance notice of his rate of pay. If the employer reduced the rate of pay after the work was done, it is doubtful that the employer can get away with this.

4 of us have been trying to help maureen and she has not returned, so we may never know more details
