Employer Suspended Me After Making Wage Claim And Now Demands In Person Meeting To Discuss Employment

Location: Pennsylvania

Is it legal to have a meeting when the DOL is investigating? Do I attend the meeting? Do I deny the in person meeting and request all communication regarding my employment be in writing?

Employer suspended me last week, told me to perform absolutely no duties. Been having issues with them not paying me proper wages that I brought up months ago but chickened out when the board member I spoke to threatened to terminate and sue me if I went to DOL. They started accusing me of theft and a board member started making it a nightmare to work for them. I live on property so I have been trying to save up to get out. I filed a wage claim last week after telling them I will have no choice as they are unwilling to resolve everything and expecting me to do work left unpaid and from here on out I will only perform my basic duties that I am paid for. After filing with the DOL I received an email stating they are suspending me until further notice and I am to perform absolutely no duties. The DOL contacted me and are investigating and said they will contact the employer if there are findings. Today I got this email:

“The Board will be at the (business) this coming Saturday, January 17th, to meet with you regarding your employment at (business). The meeting will start at 10:00 and we believe it is in your best interest to be present.

We need you to confirm attendance by Friday at 9:00 am.”

What steps do I need to take?
