Thank you for the information and your questions. Without having actual knowledge of the language of the confidentiality agreement I wouldn't be able to say with certainty whether or not you have any legal exposure. However, if it is a true confidentiality agreement, then unless you shared this information with your employer, then I don't see where the exposure would be under that agreement. However, accessing the "Dropbox" without permission may be another issue. I have no idea what exactly this dropbox is or where it is retained, but if it is the company's intellectual property, then there might be an issue of computer hacking or theft of proprietary information. That I wouldn't be able to say, but certainly if you are contact by an attorney for this company, you should decline to say anything and immediately contact a local attorney for representation.
As far as requesting a copy of your confidentiality agreement, you weren't out of line, but the employer is correct. In Maryland, an employer has no duty to provide a copy of anything that might be in your personnel file absent a subpeona or a court order. Some states do have laws mandating that employers provide this type of documentation, but not Maryland.
Finally, in term of the wage
issue. If the money that was withheld is a set or guaranteed salary, commission or bonus, then it would be unlawful to withhold it. However, if it is a discretionary bonus, then the emploeyr never has to pay it.
Please let me know if you have any related follow up questions. I would be glad to assist you further if I can.
