There is no hard and fast rule for the notice period; it depends on what is agreed upon between the employer and the employee under the contract of employment. As you have stated that it's a senior position, in such cases, there is normally no probation at all, since individuals at such a level are hired after thorough research and based on their track record. However, if the company wishes to implement a probation period, it is advisable to limit it to 6 months. Importantly, there should also be a reciprocal clause for immediate severance just in case. Employees at a senior level either tend to stay for a long time or, if it's not the right fit, they may leave within weeks. Once such an employee passes the 3-5 month mark, it can be predicted that they will stay for the long term.
Notice Period Recommendations for Senior Positions
Upon becoming a permanent employee, I suggest implementing a 3-6-9 pattern for the notice period. This means the employee can choose to give either a 3, 6, or 9 months' notice depending on their needs. Correspondingly, the company can compensate for their absence by deducting a notice pay of 3 months if the employee gives a 3 months' notice, and not deducting any notice pay if the notice is for 6 months. A notice period of 9 months is very unlikely unless it is mutually agreed upon between the employee and employer, particularly in cases where a suitable replacement is not readily available. Similarly, the employee also has the right to refuse if they have other opportunities and cannot wait for more than 3 or 6 months. Handling senior positions can be tricky at times, so it is essential to coordinate effectively with the reporting boss and the employee when drafting the clauses in the contract.
