Don't panic. Is there any Head of HR in your company? Are you new to this organization? All apples are not the same, neither in their size, shape, nor taste. I mean to point out the importance of managing human resources.
Either these Business Development Managers are not happy with the company culture, atmosphere, or policies, or they do not value the importance of the HR Department in the company. Many assume that HR is the most non-productive and least cost-effective department compared to theirs.
At times, this may not be the case, and probably their work is such that they tend to have less time to focus on administrative tasks. You can verbally ask their Head of Department to follow up. Alternatively, you can suggest to the Business Development Managers the importance and need for such notices and to take a little time from their busy schedules.
Steps to Improve HR Notification Response
When you send a notice, what procedure do you follow; is it through sending it once over email? Instead, you can start following a few more steps:
1. First notice a month ago with a deadline.
2. Second reminder after 15 days.
3. Third reminder after 5 days, copying their Head of Department and your reporting authority, i.e., Head of HR or Director (only to those who have not initiated the process).
4. Five days before the deadline - an email mentioning the names of those departments/employees who have initiated the process in a timely manner and submitted the documents. This will prompt others to do so within the deadline and avoid the need to send a new notice with a new due date.
You'll only need to do this twice or thrice, and you'll see the difference - just one notice and you are done. Start giving importance to your work, and others will follow.
