Two of my team members I look after (of a certain cultural background) had some personal issues to look after so I allowed them to use sick leave and work from home for extended periods, without the required paperwork.
Management and HR agreed to this.
Other team members' (another cultural background) similar requests were denied based on what I saw their hardships were.
Some team members noticed and started talking about it. I think this is bullying and harassment and perhaps even racism towards those two individuals. I think this is very disrespectful since it indirectly questions my leadership.
How can I stop them from talking about this? What I want is to prevent them from bringing morale down with their negativity, and concentrate on their deliveries only.
