If you have been getting “comp time” for working overtime in a week, your employer may be violating the FLSA overtime wage laws. For example, if you work 50 hours in a workweek and are told that you can have time off for this extra ten hours you are not properly being paid for your overtime work.
The FLSA requires that your employer pay you time and a half for overtime work. Unless there is an agreement between you and your employer to substitute comp time for overtime you are not properly being paid for your overtime work.
Even if an agreement exists, your employer must provide 1 and hours leave for every hour you work over 40 in a given week.
