Two of my team members, Alice and Tina were sent to attend a 3 week seminar. It is being held in the residing city. Both are good contributors to the team but I haven't observed any animosity between them.
Today was their first day. Tina had called me up and gave me an informal update about it. At the same time, she is upset about what Alice said to her. Alice is friends with other teammates in the office; so, she kept telling Tina that it would have been better if XYZ was at the seminar. It was more of mumbling and it happened 4-5 times.
Tina wants to attend the seminar but is upset with Alice's behaviour. Now, since this information was passed on to me informally, I was wondering how best to handle this as the manager for both Alice & Tina.
The options I'm currently considering are:
Call up Alice and ask her casually about the seminar and tell her in a very casual tone that she needs to make new acquaintances as she moves outside the office. No mention of Tina here.
Call up Alice and tell her that Tina is hurt by what she said. And she needs to be more open about acquaintances.
Kindly suggest other possible options.
