If you have gaps in your CV you'll need to explain these in your cover letter. Find out how to justify holes in your employment history with our example cover letter. You need to account for interludes in your employment so a potential employer doesn't misinterpret a break in your career history. If you approach it positively, it shouldn't be an issue. Talk about the gap in the third or fourth paragraph of your cover letter and explain what you did during this time and the skills and knowledge you've learned from the experience.
When you are applying for jobs, hiring managers will always notice gaps in your employment. Are you at high risk of quitting? Have you experienced performance issues or exhibited irresponsible behavior in the past? The best way is to deal with it honestly.
What about salary requirements? In fact, even if you have a line on your resume about your career break, address the issue in your cover letter as well. Do it briefly and unapologetically. See the sample below. Do not go on and on about why you stayed home.
