Can an employer ask you how many hours you worked per week at previous jobs?

They can ask, yes. You don't have to complete this on the application form, but they may ask in the interview about any incomplete info on the application.

The employer will verify the information that you provided to the prospective employer. This generally includes title, dates worked, salary, and sometimes eligibility for rehire. It's unusual to verify hours worked, but it is not unusual to be asked if the employee worked full-time or part-time.

Not a big deal, don't worry about it.

There are several types of questions that an employer is legally prohibited from asking in a job interview. For example, an employer may not seek medical information regarding an applicant, at least not before the applicant has received a conditional job offer. Questions that seek inappropriate medical information include: "Are you disabled?" "How many sick days did you take last year?" "Have you ever made a workers' compensation claim?" or "Will you require any form of physical accommodation for this job?" An employer may, however, describe the duties of a job to an applicant and ask if the applicant can perform those duties, either with or without reasonable accommodation. In addition, if the applicant clearly has a physical disability that would seem to prevent the applicant from performing the relevant job duties, the employer may ask how the employee proposes to perform them.

State anti-discrimination laws also often prohibit an employer from inquiring about whether an applicant is in a protected class, such as whether he or she is over age forty or a minority group member.

An employer typically may ask an applicant if he or she has ever been convicted of a crime. Asking whether an applicant has been arrested, however, may violate anti-discrimination laws, because the Equal Employment Opportunity Commission has stated that minority group members tend to be disproportionately targeted for arrest, and whether someone has been arrested is not an indication that he or she has actually committed a crime. As a result, an employer who asks applicants whether they have been arrested, and then excludes those who have, may discriminate against minority applicants.

Finally, an employer is also prohibited from asking an applicant whether he or she has participated in a strike in the past or performed union organization activities.

They can ask pretty much any question they want unless it's about age (over 40), sex, religion, creed, blah, blah.

Certainly they can ask how many hours you worked. This could help them determine, a) how valuable you were to your former employer and/or b) if you could handle the work environment.

Because of potential lawsuits many employers will only verify date of employment, but they are allowed to say anything they want to.

It sounds like you maybe didn't have the best experience at your last job. I don't think trying to hide things will be helpful for you. In fact, it could hurt you. Just fill out the information and WOW them in the interview.

Yes they can.

if you have a problem with it move on and don't apply
