Employment Lawyers Can Answer Your Employment Law Questions
Based on your circumstances, I do agree with your position that such demands are disproportionate, unreasonable and impractical.
I would advise to either explain to your employee that such demands are unreasonable and unlawful, or send a legal demand letter to your employee concerning the dispute.
The latter is more effective, but it would involve small costs.
In case of need, the law firm that I am part of can help you with your dispute.
