As many others said, assume that it does, by default. Do you have admin rights, including to the firmware? Can you, and did you setup from scratch the device that you received from the from the employer? If not, then it is almost 100% there is surveillance. If they let you do all the setup, then maybe 50%. Just isolate any box your employer touches, both physically and in the network sense, separate visible and sound space as possible, separate WiFi network, etc..
