I learnt last night about your leave on this Thursday and Friday and I would like to kindly remind you the bellow procedure communicated to everyone earlier this year.
There is of course no problem to take leave which are necessary for everyone. But please understand that we work as a team, that your supervisor Greg needs to be the first informed and then follow the indicated procedure with earliest warning possible.
Kindly also understand that your first priority job is to assist Greg in the sales and tour build-up. Sebastien is also assisting Greg but understand that Greg, after me, is the only one fixing the job priority. The whole job is anyway done as a team, with everyone and with a leader. This is the only way we can be successful in our endeavor.
Please take good note for the next time
