CORPORATE SHAME AT ITS PEAK - it is completely unethical to call Employees to office during the pandemic - by secretly trying to circumvent lock down rules and imposing self-carved Corporate rules/ policies overnight.
It is utmost difficult for Employees to risk contracting Corona virus infection and attend office - basis what professional values and realities, you are trying to call employees to travel to office? Who will be responsible if they contract the infection and spread it to you and others in office - as observed - masks, sanitizers and PPE kits are not 100% effective in preventing the infection.
Please get over these thoughts: Your employees don't binge watch Netflix at home with popcorn, doing household chores instead of work, taking unlimited breaks for tea/ coffee with spouse, appearing away on Skype/ IM - Micromanagement is shameful and counter-productive.
If the work delivered has been of fine quality during WFH situation in the past - there should not be any qualms in furthering the period of WFH - it is for everyone's safety!
Remember one thing: Employees repose their trust only if the Organization trusts its employees
