Hi @Chandramouli, I'm sorry to hear your work profile got deleted. To restore it, you'll need to follow the relevant steps that you may have received from your employer. It will be ideal for you to speak with them directly for the instructions.
Work profiles are usually generated when connecting to work systems, whatever it maybe, in my case airwatch. When I sign back in to the system, it generates work profile in Knox and applies corporate policies.
You may want to talk to your Technical team about how to add theat back on
