It is not uncommon in Research Contracts to include a provision restricting collaborators poaching other collaborators’ staff who have been involved with the Research Project. Such a restriction often continues after the Research Project has been completed for about 6 to 12 months or for a similar period after that particular employee has stopped working on the Research Project.
Some funders of projects will want to have a say in whether people involved with their Research Project are allowed to carry out other competing research at the same time. These sorts of restriction can be particularly difficult for research institutions. A research institution can probably never commit absolutely not to be involved in competing research; because it has so many projects going on internally, it could probably never police it.
